If I like a color and is going to use in for probably piecing in a quilt 2 yds. If I think borders 2-4. Something that would be great for backing 6-8 or the whole bolt, if its available. Found some white on white at Joann's yesterday at took the rest of the bolt 7 yds. Would have taken more if they had it. Great for backings, piecing etc.! This was also my husband's really 1st trip with me buying fabric. LOL was absolutely amazed!
