d.i.y. resin alphabet letters

The cutest sprinkle letters made with the cutest little princess. Read on for all the details you need to make your own!


Art Resin (or if you want to go all in) Bulk Art Resin

3 Silicone Beakers + Stir Sticks OR Plastic Measuring Cups with Sticks

Disposable Plastic Gloves

Short Plastic Cups

Sharpie Pen

Bowl of Sprinkles

Optional: Resin Coloring

Heat Source (matches, food torch, lighter) or Straw


Silicone Molds of Letters, Numbers, Shapes, Etc.

Large Cardboard Box, opened flat and/or Old Sheet Pan

Nail File

Nail Polish Remover (if you get any on your skin)


1. Prep your materials and work area (preferably a well ventilated space).

a. Put on your gloves!!!! So important. Do not attempt without gloves or you will be scrubbing your hands raw for days to get them clean.

b. Lay cardboard box very flat on your work surface.

c. Label one plastic cup "H" and the other "R".

2. Fill each cup 1/3 to 1/2 full with very warm water.

3. Pour hardener and resin separately into silicone beakers. Place each beaker in a cup of water (as labeled).

4. Add sprinkles to silicone molds. **This is when your little can help!**

5. Using your third beaker, very carefully measure 100 ml of resin and 100 ml of hardener.

Optional: Add in resin color of choice now.

6. Use your stir stick to slowly stir for 2 minutes. DON'T SKIP THIS STEP!

7. Carefully pour resin into molds as thick as you'd like your letters to be.

8. Pop any surface bubbles using one of the following methods:

a. Toothpick: puncture or raise to and out of the surface.

b. Fire: heat top of resin with match, lighter, or torch to incinerate bubbles

c. Straw: Very gently blow the surface through a straw.

9. Wait 10 minutes or so and repeat step 8. Repeat every 10 minutes up to an hour as needed.

10. Let molds cure for 24 hours. If resin is sticky, let sit for another 24 hours. If it is still sticky, your measurements were likely off, and you will need to start again.

11. Pop out of molds and use a low-abrasion nail file to smooth any rough edges on the back.

Notes: If you use a matte mold, your letters will turn out matte and not clear. I learned the hard way and made 3 sets of numbers using 2 different molds before I figured it out! If you want them to be shiny and clear, be sure to use a shiny mold.

Use nail polish remover to get any stray resin off your skin.

Use your letters for decor in your little's bedroom or as a great teacher gift!
