Your method makes sense to me when using Minkie or other plush. In fact I have wanted to use it for a backing but was afraid that a lot of quilting would mess up the plushness of it. So I am going to try your method. I'm a little concerned about getting a bunch of lint in the innards of my machine that I'm not supposed to access (will void warranty). Do you have to clean out your bobbin case real frequently doing it this way?
