I've been making freezer paper stenciled shirts for a few years now and it's very addicting! If you don't know what that is, here is a tutorial. I like to do a few things differently than what is explained in that tutorial. For example, I like using sponge brushes to apply the paint, my favorite fabric paint is jaquard and I'm too impatient to let it dry overnight before ripping off the freezer paper, so I just use a hair dryer on it for about 2 minutes!
Anyway, I tried combining freezer paper stencils with felt for some Christmas gifts. The one pictured above is a stenciled owl with a brown felt branch and bow. I just hand stitched the felt on.
I stenciled the dog in this one and did pink felt for the collar and bow and again hand stitched.
I think they made for some pretty cute little girls shirts! You should try it!! (at least the freezer paper part, it's so easy!)
