Sheets as a backing
I have been reading long arm services and many of them do not accept a sheet for the backing. I cannot find a reason for this. I know a lot of people don't use sheets for backing, but it seems that just as many do. I am having a long arm delivered Tuesday and planned to use a sheet for the backing to practice, play and learn to use the machine. I don't want to do this if it could cause a problem. I am getting a 12 ft majestic Gracie frame with a Tin Lizzie 18 Ram.
