This is why I always stand at the cutting table while fabric is being cut. If I notice that the beginning end is wonky I will ask the sales person to straighten that line before cutting. I just bought ribbon the other day off a new spool. It had the glue on the end. I ask if she would measure past the glue since I would not be able to use that piece. She was glad to do this for me. Just pay close attention when fabric is being cut. I do not mind letting them know that if it is wonky I will be paying for fabric that I can not use. If this is done in a nice way they do not mind working with you.
