Hmmm, I never noticed the "unwashed" and my fabric is 100% washed as I wash it before it makes it to my fabric room.
I have no problem getting unwashed squares. I figure with just squares, it's not going to cause a lot of problems.
I have problems with scents - so the only time I'd have a problem with washed fabric is if someone does use heavily scented laundry products. I can't see where sending washed fabric would cause any problems except if they ended up scented. I'd toss a pack of scented swap fabric in the outside burning barrel ASAP - scents can trigger migraines with me, and if I get a whiff of something that I think might set one off, I don't take chances.
I think I've got enough pulled from my stash to get these cut. Most are going to be fussy cut.
Question
Should I only fussy cut so everything is still straight of grain? I have some that are larger and I'd end up cutting off part of the object unless I rotate the ruler. If that is a problem, I will set those fabrics aside.
