How to Upcycle Old Crayons in 6 Simple Steps

How to Upcycle Old Crayons in 6 Simple StepsIf your kids are anything like mine, there’s a good chance that every time you buy them a box of crayons, the majority of them end up in broken pieces scattered all around the house. In the past, I used to just throw these pieces away as they were destined to never be used again. But nowadays I collect these pieces so I can upcycle them and make brand new crayons that will get used over and over again.

If you’re not familiar with the term ‘upcycling’, it basically means to reuse discarded objects or materials in a way that creates a product of higher quality or value than it originally was.

So, in this case, I’m taking discarded crayons that will most likely never be used again, and I’m making them into nice new crayons that the little ones just can’t wait to get their hands on!

Want to learn how I do it? Then make sure you read on …

Silicone Mould and Crayons

You will need:

  • Silicone mould in a design of your choice (I used this dinosaur one from Amazon)
  • A selection of different coloured crayons


1. Pre-heat oven to 100°C/212°F/Gas Mark 1. Next, work on removing the wrappers from the crayons. This can be quite tricky, so you might want to run a knife down the length of the wrapper to make it a little easier.

2. Break the crayons into small pieces and fill each of the spaces in the mould with them. I find that the smaller the pieces, the quicker and easier they melt when I put them in the oven, therefore reducing the chance of them bleeding into any of the neighbouring colours. Make sure you overfill each mould slightly, as they will melt down and take up less space.

You can see in the image below that some of the pieces of crayon in my mould look quite big, but I actually broke them down a little more after I took the picture as I was worried they wouldn’t melt efficiently.

Silicone mould filled with broken crayon pieces3. Place the mould on a baking tray and bake in the oven for around 10-12 minutes, or until the crayons have melted completely.

4. Remove the baking tray from the oven very carefully, so as not to spill any of the melted crayons. Leave on a flat surface to cool for a few minutes.

Melted Crayons5. Once the crayons have started to cool down, transfer the mould to the freezer for around 20 minutes to speed up the hardening process.

6. When the bottom of the mould is completely cool, it’s time to release the crayons from it. Start by gently pulling and stretching the mould to loosen the crayons, then push each crayon up and out from the bottom. I tend to be a little heavy handed when completing this step, and you can see from the image below that I accidentally snapped a couple of the crayons as I released them from the mould. Oops!

If the mould is still warm when you take it out of the freezer, put it back and check it again after 10 minutes. It should definitely be cool the second time around.

Finished Dinosaur Shaped CrayonsAnd, voila, you now have a nice new set of shaped crayons! How cool do they look? You’ll very often get a couple of minor imperfections when melting crayons like this. But I like them as I think it adds to their character. What do you think?

Oscar, my 3-year-old, loves it when we melt crayons down into new shapes, and he couldn’t wait to get his hands on this set of dinosaur shaped ones. He pinched them as soon as I’d finished taking photographs of them for this post and spent the rest of the afternoon drawing on some paper with them. Aww.

Have you ever upcycled old crayons in this way before?

    I dont have children, but this is such a fun and innovative idea 😉 x

  2. 03/04/2017 / 7:54 am

    This is such a great idea Louise and they turned out fab! I’ll be trying this with all the broken crayons in our craft box 🙂

  3. 03/04/2017 / 7:56 am

    These look so cool, I think I’m going to save some old crayons and make some for my daughter. X

    Wow these look great! What an excellent idea, i’m surprised i’ve never seen these before!

  5. 03/04/2017 / 11:03 am

    OK this is absolute genius! Totally sharing with my friend for when her bairn is a bit older

    What a genius idea. I love it and must give it a blast, we have lots of crayons that this would be suitable for x

  7. 03/04/2017 / 2:46 pm

    This is such a good idea, I’d have never thought to recycle old crayons, but I bet kids get through so many of them x

  8. 03/04/2017 / 4:16 pm

    A wonderful idea 🙂 I hate throwing things away so this is a perfect way of recycling ! xx

  9. 03/04/2017 / 4:59 pm

    This is literally such a cute idea for making good use of broken crayons! I love the little dinosaurs they are so cute x

  10. 03/04/2017 / 6:56 pm

    This is such a fab idea! I love the idea of upcycling anyway, I do it all the time with my candles so it’s great to see new projects. I’m all for reusing things and it totally saves money.

  11. 03/04/2017 / 9:01 pm

    I love this idea – we have so many broken crayons every day! I will definitely try this. Kaz x

    That’s such good creative idea, I think every child will love dinosaurs crayons. xx

  13. 04/04/2017 / 8:06 am

    I saw this on Pinterest and thought what a fabulous idea! I remember how annoying it was to get down to a tiny piece of crayon, especially when it’s little fingers holding them, and I hate waste, so this is a perfect solution!

  14. 04/04/2017 / 9:46 am

    Aw wow this is such a cool idea!

    we love doing this too. we have some alphabet moulds which are good fun and I’ve given children’s names in crayons for gifts before now x

  16. 05/04/2017 / 7:57 pm

    That’s so much fun! This is such a great way to get more use out of all those busted crayons we have floating around the house.

    This is so cute!! I hate having waste around (and with kids and crayons there is always a ton!). This is a great way to use up left over crayons!

  18. 05/04/2017 / 8:31 pm

    Now that is just a perfect idea! Love it! We used to melt old crayons between wax paper and make stained glassed “windows” – this is an even better and more functional idea!

    Now, that is brilliant! Those new crayons are the cutest things ever! I wish I had known about this when my kids were little and we went through crayons like crazy.

  20. 05/04/2017 / 11:52 pm

    When you have kids, broken crayons are a way of life. I love how creative you were in upcycling them! Bravo!

  21. 06/04/2017 / 12:53 am

    I’ve always wanted to make fun crayon molds like these but have never gotten around to it. I should grab a cute mold like you have and make something!

  22. 06/04/2017 / 3:27 am

    Brilliant! And the end result is perfection! These would make wonderful little party favors and I’d feel so good about using all the broken bits to make something!

  23. 06/04/2017 / 5:53 am

    Omgosh this is beyond adorable. I want to try this project. The dinosaurs are so stinkin cute!

  24. 06/04/2017 / 8:27 am

    You are right, buying a box of crayons seems endless. This is a brilliant idea.

  25. 06/04/2017 / 12:02 pm

    This is such a great way to use up those crayon stubs. They would make great additions as party favours in gift bags too.

  26. 06/04/2017 / 10:05 pm

    That is such a cute idea for upcycling crayons! My kids would love this!!!

    My son prefers markers over crayons. Yet, as a momma, I’d prefer he’d use the less of a mess crayons. I do think having dinosaurs to color with might interest him a little more.

  28. 07/04/2017 / 6:55 am

    I did this with my kids too, but I used multiple colors to make one giant crayon. Definitely a great way to upcycle bits of broken crayons.

    Who would have thought that you. Oils make something that cool with old, broken crayons. What a fun project to work on with the little ones.

  30. 07/04/2017 / 2:46 pm

    I have not done this yet but it is on my list to do for my son’s birthday party this year as part of the goodie bags.

  31. 07/04/2017 / 4:24 pm

    Awesome! My daughter is a little older but she still has a giant stash of broken crayons. Upcycling is her favorite word (seriously!) and she would love to try making cute shapes out of those broken crayons.

  32. 07/04/2017 / 4:59 pm

    What a fun idea. My Mom used to do this when I was little. Of course our methods were archaic back then. Love the upcycled better than the new with this mold.

    Those dinosaur molds are just too adorable! I need to do this with all of our broken crayons.

  34. 07/04/2017 / 8:31 pm

    This is such a good idea! I have never thought to do this. These would be a fun gift for a child’s birthday, thank you for the idea!

  35. 07/04/2017 / 11:13 pm

    I have tons of old crayons here from the kids. We did this once, but I would like to do this again and then gift them! Love the dinos!

  36. 08/04/2017 / 7:57 am

    Oh my goodness I love this idea! Wish I knew about this when my son was younger!

  37. Jacqui Odell
    08/04/2017 / 10:08 pm

    What a cute idea! You know what? I have that exact mold!

  38. 10/04/2017 / 10:40 am

    I love this upcycle crayon ideas. I wish I knew this as a kid I had so many crayons I could of made fun molds with. It would be fun to make multicolored crayons by putting lots of different colors in one mold.

    Oh this is awesome what a great idea to go with old crayons. awesome. I am baby sitting on wednesday and she would love this.

  40. 11/04/2017 / 7:47 am

    Not only is this a cost effective practice to save a bit of money, but its a good activity to get the kids involved in at a young age to start to understand the importance of ‘upcycling’ or even ‘recycling’ for the environment. So they effectively end up getting a new gift (the recycled crayons), learning about the environment and also having fun seeing the whole thing happen. Genius!

  41. 11/04/2017 / 8:50 am

    What a great idea! My kids are a little beyond this now but a great tip to keep in mind….. maybe for grandkids in the future!

  42. 11/04/2017 / 10:14 am

    Beautiful. I will try it with my little daughter, she is already into her summer holidays

  43. 11/04/2017 / 12:47 pm

    Such a great idea! Congrats for the creativity! This is great not only for kids, but for playful adluts like me. 😉

  44. 11/04/2017 / 3:15 pm

    This is such a fabulous idea, I am going to try it now with my little girl. She will be thrilled since we have so much unused crayon. Thank you so much.

  45. 11/04/2017 / 7:26 pm

    I love this. These kids here have so many crayons that never get used up because they always want new ones at the beginning of every term. All I need is a silicone mould, I will use Lou’s style to upcycle those crayons.

  46. 11/04/2017 / 8:54 pm

    Sooo cute!
    They look edible though!

  47. 13/04/2017 / 9:00 pm

    Oh wow sooo cute! Love this idea!

  48. 13/05/2017 / 1:16 pm

    This looks like great fun. #ablogginggoodtime

  49. 15/05/2017 / 9:50 am

    Love this! One year we made mixed up crayon discs by putting different colours together in round moulds. The result was really pretty and super-fun to colour with! #ablogginggoodtime

  50. 17/05/2017 / 8:16 pm

    great ideas for no waste!
    Thanks for linking to #ablogginggoodtime Please join us next week too!

  51. 06/06/2017 / 12:50 am

    I love this! Anything to avoid having to spend money, and make less waste? Brilliant! I’ve even upcycled candles by taking the last little bits of wax and melting them over a double boiler and putting them in a freshly cleaned jar with a new wick. Such fun!!!

    Awesome post! I love it! I wish I had thought of this when my kiddos were young!

  53. 19/02/2018 / 12:28 am

    I keep meaning to do this with all the random pieces of crayon that I find scattered around the house! Really must get round to it 🙂 #bloggerpinparty
