HST binge is an apt description. : ) I did something similar to try to cut into my stash of fat quarters. I cut 10 inch squares out of a bunch and made eight at a time (4.5 unfinished/4 finished). That way I'd have some building blocks for a variety of designs that use HSTs. I have over 200 now. I should probably get busy and make something!
I confess I did the same with the 4 at once Flying Geese blocks because they also get used in a ton of designs. I haven't used those either and I have over 200 in several different sizes.
Maybe this is akin to having a stash of hexies ready to use? No concrete plans but there when you need them. Post pictures when you choose a design!
