I think this is an excellent tutorial for how to deal with strips that I didn't cut quite right, which has been known to happen. But I see no reason why I should have to learn to "deal with" strips that a manufacturer didn't cut quite right. Those shouldn't be sold, IMHO. If a strip is as much as 1/8" too narrow (as stated in the article) that means my seam allowance will be only 1/8", and that's not acceptable. Why would I spend the money that Bali pops are commanding to wind up with a 1/8" seam allowance?
