If one has a piece of $12.00 yard fabric - and lose 2 inches of it due to fraying (one inch from each end) - That's about $0.67 of fabric that was lost.
At $10.00/yard - That's only about $0.55 of fabric that is lost.
Doesn't make sense to me to waste fabric like that - especially when so many people are crying about the high cost of cotton fabrics.
