hi edie,hope you and your husband are doing well. I have a question that i hope you can help me with. I took a class on how to run a longarm and I'm going to rent time to actually finish my first bedsize quilt, and they said I have to have the top and bottom squared up. How do you do that. I'm not to get with measurements. Probably kind of a dumb question huh? Thanks Edie. Tammylou
