Harmony--I never owned one until there was one the perfect color for a scrap log cabin I was making. I just cut it into strips. I've never known what purpose they served compared to buying yardage. I recently bought more on sale at Joannes for barns/grass--and since this pattern called for fat quarters and the directions were going to go easier if I used them, I hunted around to find some that'd work.
I still don't know the advantage over yardage except cutting ease? FQ at one shop were $2.50 each! That'd be paying $10 a yard!! The owner said no one thinks of it like that. :lol: I'll buy them if they're $1 or under.
