I created these with a freezer stencil. I had yet to try it and I'm glad I finally did. So. stinking. easy!
Start off with a basic tee (or two, in my case).
Find a stencil or silhouette of a truck and size it to however you like. I used this stencil.
If your image isn't bold enough, trace around it with a felt marker.
Then trace it onto your freezer paper.
Cut out your shape using an exacto knife.
Be sure to keep any inside shapes or pieces, like the windows.
Once you have your stencil cut out, center it on your shirt (waxy side down). Be sure to place your pieces and iron in place. Just a quick press is all you need to ensure it sticks to the fabric.
Slide a piece of cardboard between your shirt layers to give yourself a flat surface and to prevent it from bleeding through to the other side.
I used a black fabric paint and a sponge brush to paint my trucks on.
It's mostly a dabbing motion that you'll be using to paint it on, being careful along your edges.
Give it just a few minutes, then remove your stencil. It'll come off like a sticker. You can use an exacto knife to remove your small paper pieces. Set it aside to dry for the day or overnight and you are done!
My boys chose which trucks they wanted on their shirts.
I like their choices. They can't wait to wear their new shirts!
See? Simple and boyish!
