Tip To Easily Peel Crayon Wrappers

Soak the crayons in warm water for about 10-15  minutes. Some of the papers will just fall off while others may need a little extra help. Twist your hands over the paper to help get more of the crayon papers to come off easily.

If you don’t want the hassle of peeling the wrappers off, you can consider buying bulk unwrapped crayons to use for your letter crayons.

How To Make Alphabet Crayons

Step 1: Take The Wrapper Off

Peel the crayon wrapper off of the crayons. Soaking in water for 10 minutes can really help with the process.

Separating the crayons by color will help you quickly fill the molds before melting.

Step 2: Preheat The Oven

Preheat the oven to 275 degrees Fahrenheit.

Step 3: Fill Molds

Place broken crayon pieces in molds.

Fill in the letters as much as you can. The crayons melt to fill every empty space.

Step 4: Place In The Oven

Put letter silicone mold on a cookie sheet before putting it in the oven.

Step 5: Cook Until Fully Melted

Cook for 9-11 minutes or until fully melted. Make sure to watch for when they are fully melted. You do not want to overcook them.

Just like with baking, times may vary. We would rather cook them at a lower temperature for longer.

If you have one stubborn crayon that won’t melt, you can take a toothpick and stir it with the hot wax to try to melt it quicker.

Step 6: Pull Out Of The Oven

Once you see that the crayons have fully melted, pull them out of the oven immediately. The wax will be very hot and liquid.

Step 7: Let Crayons Fully Cool Down

How long your newly formed crayons need to cool will depend on the size of your molds. You will know the letter crayons are fully cooled when they are not warm to the touch and have a little white appearance to them.

Step 8: Remove Them From The Mold

Pull the edges around the mold first to help loosen your new crayons. Once one is completely cool to the touch, you can carefully push it out of the letter mold.

Factors That May Change Your Melting Time

  • The size you cut or broke your crayons. Small pieces will not take nearly as long to melt as larger pieces
  • Different colors also will have different melting temperatures
  • Your molds are of different sizes
  • Your oven runs differently
  • The brand of crayons used

As long as you are watching your crayons, you can change the cooking time and oven temperature to work for your crayons and oven. As with any baking time, oven times and temperature may vary for your specific situation.

You could try to cook these new crayons at 300 or 350 degrees for less time. We like using lower heat and longer times to limit the fumes.

Ideas For Gifting

These letter crayons make an awesome gift, party favor or stocking stuffer. Here are a few ways you could consider gifting them.

  • In long clear bags with a ribbon
  • Create a DIY gift tag to add
  • In small boxes with tissue paper or other filler

Craft FAQs

What brand of crayon is best for making crayon letters?

Any brand of crayon will work, just note that each brand has a different melting time. Therefore, if you mix brands you will need to keep a good eye on them while in the oven.

How can I fix broken crayon letters?

If you take the crayon out of the mold too soon, then they may break. Place the crayon back in the mold and reheat it until it has melted back together.

How to pick crayon colors for new melted crayons?

Colors that are similar will mix better together than if you try to put every color of the rainbow in. You can try a rainbow crayon if you watch it carefully and immediately pull it out before all the colors mix into an ugly brown.
