ALot of the letter jackets you sew through the wool and the thick lining and you don't always need backing but the one time you don't use it is the time something doesn't line up right or a mistake happens and its harder to take out. I very rarely use less than a double 3 oz peice of backing on my jacket backs. As far as hooping hoop it fairly loose and then tighten after hooped and make sure you pull out any wrinkles. hoop the backing is my recommendation. YOu may be able to just slide it under but I prefer to hoop backing in whenever possible. =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
