I found myself buying fat quarters when shopping in store recently because they meant less contact with the employees compared to have yardage cut. I actually prefer skinny quarters because I typically make scrappy blocks using small pieces.
On the other hand, I don’t understand people who have yards of fabric in their stash. I will buy a yard or more only when I have a specific purpose or it’s a really good deal on sale (especially if I am trying to make a shipping minimum). Bottom line, every quilter is different.
