Please clip loose threads, if sending backing make sure it's at least 6 inches bigger (8in better) than your top and squared, also please NO salvage if it's a pieced back, if no borders stay stitch 1/8 inch all around to keep from pulling apart at seams. No deep creases in the top or backing.
These are the things I ask for, and will need to charge extra if I have to do them.
It's very nice of you to ask. Your longarmer will appreciate it very much. And a happy quilter is always a good thing. ♡
