Hi Resin Crafters, it’s Natalie from Doodlecraft sharing a fun FastCast Resin craft making letterboard letters. Letterboards are so much fun to write funny quotes, lists, menus or party themes. Learn how to make your own resin letterboard letters using FastCast Urethane Casting Resin, some toothpicks, stick-on jewels and just a few minutes!
Recently I bought some small letterboards but they did not come with any letterboard letters. I decided to make my own letters using Castin’ Craft FastCast Resin. This type of resin cures fast, in just 15 minutes. It dries white, not clear, so it’s great for resin applications that don’t need to be see-through.
This resin project also works great if you are doing just a few specific letters, rather than trying to mass produce every letter in duplicate for future use. If you have a silicone mold, you can turn it into a letterboard pin using this trick too. Let’s get started.
Supplies Needed for Fast Cast Resin Letterboard Letters:
- FastCast Resin (8 oz is plenty)
- Alphabet Silicone Mold
- Mixing Cups, Stirring Sticks, Disposable Gloves and Worksurface
Step 1: Cut Toothpicks
Begin by cutting the pointed end of the toothpicks off with some scissors. The cut-off blunt end will be inserted into the resin while curing to latch into the letterboard. The resin cures so quickly, these toothpick pieces must be ready to use.
Step 2: Mixing Fast Cast Resin
Secondly, take the time to read through the resin mixing directions contained in the package. This resin only needs to be mixed for a minute, then poured into a second cup and stirred with a new stick for 30 more seconds. It’s important to read through the directions to ensure proper mixing and curing.
Step 3: Filling Silicone Mold
After the proper 2 phase mixing process for the Fast Cast Resin, use the mixing stick to pour the resin into the mold. This part can get tricky and messy because the resin thickens and sets up very quickly. I have a solution for this, that I call “editing”…but you can mix up less resin and work a letter or 2 at a time if that feels better to you.
I used 1 tsp of each the resin and hardener, so 2 teaspoons and was able to create 11 letterboard letters.
Step 4: Toothpicks
You will see the resin almost instantly begin to turn white. Work quickly and insert the toothpick pieces into the top part of each of the letters, starting with the first one filled and so on. The toothpicks should have no trouble sticking in place because the resin cures so quickly. Place a toothpick in each letter and then let them cure for 15 minutes.
After 15 minutes, the resin letters can easily be removed from the mold. If the pour was very clean, the resin letter will be ready to use.
If there is any drips, puddles or lines, there is an easy fix.
Step 5: Editing
If there is excess resin around the letters, there is still a little pliability in the resin after 15 minutes of curing time. This makes it very easy to trim off the excess resin using some small scissors. If a hole needs to be opened up, you can use a drill and a small hobby knife…or just leave the hole filled for a different look.
Now the letters are ready to use, paint or decorate! The toothpick top shows a little bit on the top edge of my letters. I decided that I could either paint the letters or add some jewels…which is what I decided to do.
Step 6: Embellishing Letterboard Letters
I used adhesive jewels in various sizes to fill the top of each letter with a little bling. This can be done with gem tack and flat back rhinestones or adhesives like these. This made it a really quick embellishment process and I love how they look!
Creating the perfect letterboard letters for a simple business sign, party or special occasion is easy using FastCast Urethane Casting Resin. It’s a fun DIY using this quick setting resin. Make a custom piece in less than 20 minutes.
We’d love to see if you create some letterboard letters too! Tag us in your posts on instagram @resincraftsblogbyeti so we can cheer you on!
