This little hanging bag is from Kwik Sew 3748. (I think it's out of print?)
A LOT of my patterns are out of print, and not just the vintage ones. I think this is because I get about 60% of my patterns at Goodwill and another 35% were grabbed up when the Hancock fabrics near my house was closing (as were they all).
Anyway, for anyone out there who has this pattern - I like it! I only interfaced the outer fabric. The inner fabrics are quilting-weight cottons. If I ever make it, again, I'll interface everything. It feels a little wimpy, as it is.
The hardware at the top was one of the more difficult things to find. I ended up buying a smaller, somewhat ripped-up bag at Goodwill and scavenging the hook from that. It was cheaper than anything else I could find, and had a swivel, which I hadn't seen in the two fabric stores I checked.
