I have given up on trying to cut long strips without getting a V at the fold. Plus I find them a pain to work with--especially at the ironing table. So, usually I just cut the fold off so I have 2 short strips instead of one long one. If I need subcuts that would make it impossible to cut the fold off (like 8" strips), I will cut the 8" pieces leaving the last one at the fold for later. Then I take those pieces to the ironing board, spritz them with water and press them into shape. If one is really wonky, it goes into the scrap bin.
