What better way to celebrate Valentine’s Day with your little ones than by creating some adorable handmade gifts? Today we’re melting crayons into heart-shaped molds to make the cutest DIY Valentine’s Day gifts! This easy and fun craft is perfect for kids of all ages, and the results are sure to brighten anyone’s day. Let’s get crafting!

Mimi and Me: Get Crafty with Us!

Crafting with kids is a fun past time and makes me feel like a kid again! This month my granddaughters and I made these easy melted crayon hearts. The craft is perfect for little hands and big imaginations. Our melted crayon heart project is a great way to spend quality time together and create something beautiful.

We actually made these for my oldest granddaughter’s preschool class. She is going to pass them out for at her Valentine’s Day party!

Come along and see how we did it!

Gather Your Supplies

This project is made with all those old broken crayons you have in the crayon box. Some of my new ones seem to break the minute I get them out of the box – little hands at work and I don’t mind a bit!

Most everyone has a stash of crayons that they can use. The other supplies are few and you may have most of them in your crafting supplies.

Prepare Your Crayons

You need small pieces of crayons for this project, so the broken ones you have are perfect for this DIY. If you have larger pieces that you want to use you will want to break them into smaller pieces to fit inside the mold. I did take the wrapper off of a few new crayons, to get a broader range of colors.

My littles thought it was so funny to be told they could take the wrappers of the crayons. Every time we’ve colored since making these DIY crayon hearts, my 2 1/2 year old granddaughters think they should be taking the wrappers off each crayon. I have to remind them that we don’t always have to remove the wrappers. Funny little moments!

Sometimes the smallest things bring the most joy. Breaking the crayons into tiny pieces was so much fun for my grands. I always say to look for the little blessings every day and watching them laugh while snapping each crayon was definitely a blessing and a memory maker!

Melt the Crayons

Once the crayons were broken into small pieces, the real fun began. We carefully filled each heart-shaped silicone mold, combining different colors for a vibrant, swirling effect. Pink and purple, or green and blue combined together in some, while others showcased sunny yellows, greens, and oranges. I did use very small pieces of white in a few of the molds, just for something different.

I baked the crayons in the oven on 225℉ for 20 minutes. After 10 mins, I checked the molds and determined that some of the molds needed more crayon pieces. Add to yours as needed.

A few helpful tips

  • Choose the right crayons: Use regular wax crayons, like Crayola. Avoid specialty crayons (like glitter or metallic) as they may not melt evenly or could release harmful fumes. Remove all paper wrappers completely. This is a crucial step!
  • Prepare your molds: Silicone molds are ideal because they’re flexible and make removing the finished crayon shapes easier. You can also use metal molds, but grease them well. Avoid plastic molds that could melt.
  • Check the melting: Check the crayons after 5 or 10 minutes to make sure they’re melting evenly and not burning. If you are unsure if there are still tiny chunks, use a toothpick or skewer to gently stir the melted wax.
  • Adult supervision: This project should be done with adult supervision, especially for younger children.

Cool and Remove

Once your crayons are completed melted, remove from the oven and set them aside to cool. I let mine sit for about an hour before I tried to remove them from the mold. If you are using a silicone mold you can actually pull the mold away from each heart.

Decorate and Present

Each step of this project is fun! Creating the Valentine’s Day bags to pass out was also exciting for my grands.

Below is my FREE Valentine card template that you can print out for your DIY hearts! There are four cards on a sheet. I used cardstock for mine and adhered each heart to the card with a small drop of glue from my glue gun.

Share the Love!

This DIY melted crayon project was such a fun and interactive project to do with my grands. Not only is melting crayons a enjoyable activity, but it’s also a great way to recycle those broken crayon that would otherwise end up in your trash. Give them a new life and create something beautiful in the process. It’s a win-win!

  1. Very cool idea! I remember as a kid making Valentine art with grated Crayon pieces melted between 2 pieces of wax paper & heated with an iron. c1960s. Much safer in the molds & more fun too!

  2. I’m getting all kinds of teary in the best possible way because I used to do this with my Granny too, Kim! I love that you and your grands do so many crafts together. It’s such a special way to learn new skills and to be creative. Can’t wait to share this for my back to school/embracing August post. I know it’s going to be a big hit! Hugs, CoCo

    1. You are so kind! My oldest granddaughter really counts on the craft time with me. The twins are only 3 so although they like to do it too, my oldest really enjoys it! I’m so glad you have those special memories with your granny! Those memories make our worlds go round! Thanks for the share, CoCo! Be blessed this week! xo
