I usually buy 2 yards of blender fabrics unless it is one that I know I will use a lot, then maybe 3-4 yds.
If it is a print/focal fabric that I am absolutely in love with, I will buy 3-5 yds.
Any more, I tend to stick to blenders for just stash collecting, and I am getting more picky on the prints I get. This is subject to change... as two years ago I bought more prints than blenders ROFLMBO :D:D:D
