Honestly I am not sure but I know there must be 50 double and larger tops to be quilted. I do a lot of doll quilts for the quilt guild I belong to and make tops for Quilts of Valor, and various other tops. My stuff always seems to get made in tops and then they are put up. I have a mid arm and hope to get it figured out. I don't know how to load it so I just keep making tops. I get all my table toppers, wall hangings, and small things quilted but the big stuff in just stored away until I figure it out. I wish I knew how to load the quilt but as yet have not figured it out. This is my goal this year.
