Our friend, Kai, LOVES school buses. He had a school bus party for his 6th birthday and the boys were invited.
We went to Joann's to get him a little glue gun for his gift (he really liked using Aaron's low temp glue gun at our house) and saw this little bus patch. It was so perfect so I grabbed a plain black t-shirt as well.
When I got home it looked so plain. I thought it would be cute, and hilarious, to add some flames. So that's what I did! I simply painted them on with several coats of acrylic paint. I had a board inside the shirt so that the paint wouldn't bleed through. You can mix your acrylic paint with a bit of fabric medium (found right next to the little bottles of acrylic paint) and that will help it set right in the fabric (a softer texture when it dries and less cracking after many washings) than just using acrylic alone, but either way works and is permanent.
Once acrylic paint dries, it is permanent. I know this because I've ruined several shirts while crafting over the years.
After it was completely dry, I ironed on the patch. I sewed around the patch as well to make sure it was sturdy. I also ironed the back of the flames to heat set them.
A one of a kind birthday gift (along with the glue gun) for a one of a kind little guy.
