I usually buy 2 yards at a time when the fabric is on sale and I don't have a definite project in mind. That way I have plenty for just about any project.
I checked out the on-line store and their prices are good -- $3.99 a yard. BUT they have no ruler reference, so it's impossible to tell how large the motifs or prints are. What a shame as it might have been a good resource for economical fabric.
