I got this idea a few years ago and have been saving leftover crayons. At the end of last school year, our district came down with a new rule that said we can no longer give out any candy. I suddenly got motivated to put my plan in place.
Any teacher can make these wonderful molded crayons for their classroom. I definitely have my work cut out for me since I am a music teacher and have over 500 students.
Every year, I have a theme of the year and my student of the day sits on my VIP chair and gets special privileges, such as leading games and helping the teacher. They used to get a piece of candy. They will now get one of my molded crayons! Check out my post about my VIP chair.
I also do a raffle for my 5th and 6th grade classes and choose a couple of tickets a day. I am amazed at how much they learn and how many things they will do, such as sing a solo to earn a raffle ticket. They also used to get candy and will now get a molded crayon!

I have streamlined my molded crayon making system. Hopefully, my trial and error will help you avoid some problems.
STEP ONE: Gather or buy crayons
First, gather crayons from teachers who don’t need them anymore, friends in your neighborhood, local restaurants, etc. I have found that Crayola crayons are much easier for getting off the paper. You can also buy crayons. Back-to-school sales are the best. Back-to-school sales are a great time to get new crayons. In the last couple of weeks, I found Crayola boxes of 24 crayons for .50 at Target and Walmart and an off brand for only .25 a box, but the paper is harder to get off.
EDIT: I actually got a donor’s choose grant for 250 boxes of crayons this year.
STEP TWO: Get silicone molds
I have gotten carried away and bought a number of molds. There are tons of them on amazon, ebay, and etsy.
Here are ones I bought:
Here is where I got molds:
Edit: Since I posted this, some of these items are out of stock, so go to ebay, amazon.com, and etsy and search for silicone molds to find some fun ones. I did buy some really inexpensive ones from china that ended up being super tiny and wouldn’t work, so be sure to check the size of the mold in your description. If you have funds, people on etsy sell these molded crayons as well.
***IMPORTANT- Even if a mold says silicone, be sure to check to see that it will work in an oven. I found two molds that said silicone that melted. When I went back to look at the description, it said not to put them in the oven.

Skull and Crossbones
Animals (bear, hippos, lion)
Treble Clefs – From ebay but now out of stock
Hearts- I can’t remember where I got these. It might have been Walmart or Hobby Lobby. If you look online, you can find them in other places.
STEP THREE: Sort crayons into like colors
I have found that kids love to do this. If you have huge numbers of used crayons, have them sort them into similar colors. Then sort further into more precise colors and put them into ziplock baggies.
STEP FOUR: Take off the paper
This is probably the most challenging step if you have used crayons, but I have some tips for you. First if you put them into very warm water (not too hot or they’ll melt all over). If you have new Crayola crayons, most of the papers will just come off and for others, just slide the paper down with your fingers. That will take off the glue. For used crayons, many will come off with warm water but some will be harder. I have been getting the easiest ones and then dumping the water and getting more warm water. It is definitely more challenging. The few ones- usually an off brand of crayons- that are almost impossible, I throw away because I am doing such a high volume, I don’t have time. I have a plastic tub to put my depapered crayons in. Then I dry them all and put them back into the ziplock baggie.
I actually invited a few choir students to come and help with this. They had a blast and even had races to see who could do it the fastest!
STEP FIVE: Cut them into small pieces
I first started using scissors, which didn’t work well and then tried a large exacto knife. It worked better but my husband found the best way. It is a utility knife we’ve had forever with a razor blade. I looked online and found a U-Line knife. He just chopped straight down on them using a cutting board and he was able to do it so quickly!
STEP SIX: Put the crayon pieces in molds
Put the crayon pieces in molds and put them onto a cookie sheet. I put several molds in at a time. I have found that for me since I am making large amounts of these, I put all of the same colors in at a time. At first, I was chopping and putting varied colors in the same mold. It ended up mixing up the colors a little bit. If the pieces are already cut, you could probably do varied colors in one mold and it would work fine. The smaller molds take only 1 crayon. The larger ones, such as the skull and cross bones take 2 crayons if you want to fill them up, but you could definitely do only one and they will just be thinner.
STEP SEVEN: Put the molds in the oven
Preheat your oven to 250 degrees and bake for 15-20 minutes. When you look at the melted crayons, they should be totally liquid. If you see any lumps, leave them in for a little bit longer.
STEP EIGHT: Let cool and remove from mold
Be sure to let them totally cool. If I get impatient, I stick them in the fridge to cool. Be careful getting them out of the molds. Most of them were easy. The guitars were easy to break the neck, but once I figured out how to get them out, it wasn’t too hard. I had to be careful with legos to be sure the top pegs don’t come off. Again, be sure they are totally cool.
STEP NINE: Clean up the mess
I would immediately clean up your mess of the little bits of crayons that chip off as you are cutting. I didn’t clean up right away and we had company coming. My husband used our steamer on the floor and it left small crayon streaks. I just used a Mr Clean “Magic Eraser” to easily get it off. Also, let your molds sit in very warm water for a few minutes and then wash your molds off. Another trick is to put them back into the oven to let the leftover bits melt and then clean them off. I would use a little scrub brush (not too rough) if you have one. You want the mold to be pretty clean before you put another color in it.
EDIT: We have found that getting a box lid, putting parchment paper (newspaper would work too) under the cutting board, and then cutting that makes a big difference to keep the mess down.
I intend to let my students choose a molded crayon, so I put them into a set of drawers I already had in the classroom. I also found a smaller one with drawers that students can choose from.
Once you are done, enjoy! I can’t wait to give them to the kids!
Edit: I am now a few weeks into school. The kids absolutely LOVE these, even my 6th graders. They treasure them and show them to other students. Other teachers and administrators are telling me how much the kids love them. It is a big hit. I just ordered a Pikachu mold on amazon. Get it here.
