Freezer paper is so awesome!!! It is easy to cut and just irons right on to the fabric, this gives the stencil nice crisp edges. I also iron freezer paper on the back so the paint doesn't seep through. I used regular acrylic paint mixed with textile medium to make a permanent design. I dabbed (straight up and down) the paint on with a make-up sponge. The paint needs to set for 24 hours and then it needs to be heat set with an iron.
While I waited for the paint to dry I cut coordinating appliques out of fused plastic dollar store bags.
Here's the finished design after peeling the paper off, I really like how it turned out.
Next I'll need to sew the pockets and zipper onto the lining and then I'll start constructing the bag. I also have a resin project curing that will also be used for this bag, but more about that later.
