You want to make sure all your seams are ironed flat. For us, this is the most important step to producing a high quality product. Check for loose threads on the top side; we will remove if you miss a few. Trim all long hanging threads at the seams.
It is not always easy to make a perfectly squared quilt. One way to check your quilt is to measure across the top, middle and bottom. Take these measurements top to bottom and side to side. Depending on the quilt pattern and boarders you may be able to trim the edges to square your quilt. If you are only off by a 1/4″ it’s probably not a big deal but, no more than 1/2″.
Make sure the batting and backing have at least a 4 inch allowance on all sides. The best way to calculate material needed is to measure the length and width of your quilt and add 8 inches to the length and the width. It’s okay to leave the selvage on your backing outer edges. The selvage will need to be removed from any seams in the backing. Absolutely no selvage in the top quilt. Selvage causes problems during the Longarm stitching process. Also, the shrink factor in the selvage is different than the material. Remove the selvage!
