When I joined Columbia Stitchery Guild in the 70's, they said I needed to make a needlecase, so I did and am still using it. We didn't know much about archival things then and inserted cardboard to make the cases stiff. That's breaking up and crumbling.
Since I enjoy felting and stitching on felt, it seemed like a good project to replace the needlecase. Above is the front.
It's hard to see on the off-white pages, but this center one has pockets. The old one doesn't and it's handy to have a place for a needle threader.
