Almost all of the department stores sold fabric including Bambergers (now Macys). I had forgotten about that measuring gizmo, it sure was cool. Pennys was directly across the mall from Woolworths, so I'd compare the two for price and selection. Bambergers (also in the same mall) sold mostly wools and high end fabrics.
Those were the good old days of sewing! Now I only have a crummy JoAnns and the intenet.
