It will turn up. It's just having a little holiday somewhere. Last year I pulled my whole sewing room to pieces looking for some binding I had cut ready to finish a quilt. Didn't find the binding, but found heaps of other interesting stuff. Eventually the binding turned up in a cupboard in another room, where I'd carefully placed it so I'd have it to hand when I needed it!! After all that, the binding didn't suit anyway, and I was off to the shop to find something else. Be patient, your kit will appear again when it's ready. Something to look forward to.
