I just got my machine and missed the lessons because they had them before I purchased. I am going to put an embroider butterfly on a small denim purse for a grandaughter, so I imagine the sticky self adhesive Sulky will work. But if I embroider pillowcases or dishtowells do I still have to use that or can I go to a lighter weight tear a way or wash a way?Does it always have to have a sticky back or can i use a spray adhesive with a wash a way on those two items?
