After reading some of the comments again...those of you finding you lose significant amounts of fabric when you straighten, think about how many other cuts were made before yours from that same bolt of fabric. Look at the ends of fabric bolts someday; you will see 8-12 inches of crooked fabric. If the edges were ripped or grain straightened when the bolt arrived in the store, we wouldn't see so much waste. Straight grain is present in every yard of fabric; the store should make it correct when they sell the first fabric off the bolt. Think about it...
