This is a great craft which even younger children (4+) can make as Father's day gift. These key chains was completely my son's idea. He did the needle work on these star shaped plastic canvas that can be purchased at any craft store. It started as a part of stitchery work at his school. He loved doing it so much, that I got him few patterns for the summer.
He liked these star shapes the most. These are around 4 inches, not too small, but can work as a key chain. He chose all the colors for these stars, some were embroidery threads mixed with knitting yarn.
We backed it with felt using hot glue. Added the keyrings, packed in small bags, and shipped all the way to India for Grand Pa.
Happy Crafting with your kids!
