Yesterday my local group had its monthly meeting, and we learned how to make click-it bags. Those are the bags that use pieces of metal measuring tapes to keep the top closed. I made one and discovered that the size we were doing was absolutely perfect to solve a little problem I'd had.
Last fall I bought a Martelli rotary cutter, which I love (cutting out those 1200+ pieces for the Winding Ways quilt I'm making wasn't a strain at all!) but which is definitely not going to fit into any rotary cutter case I've ever had or seen. However, it fits quite nicely into the little bag I made yesterday, leaving space for spare blades and even a marking tool or two, if I want. :) Yay!
I posted a photo of the bag on my blog (URL below), but I'd probably choose different fabrics if I were to do it again; I didn't quite understand how they were going to go together when I was selecting my fabrics. :S Oh well -- my rotary cutter doesn't mind.
