This is a project that I started and completed a few months ago. I took an old cosmetic bag I had that was falling apart, took the seams out, traced the original fabric, and transferred the pattern onto "new" fabric (the khaki on the exterior is from an old pair of pants).
I used gray and green Amy Butler fabric on the inside and for the exterior strips, and used pink binding tape to hide the zipper's edges.
The zipper is the one from the original bag. I also sewed a "svea" tag to the exterior.
