I used heavey weight fusable interfacing. for all the fleece.It seems to be standing up well. I have made 14 mini bow tucks this way.The inner pocket is too long even if it is cut in half. I do mine the width of the purse. Also I use to pieces of plastic canvas for the bottom inside. I cover it with a pillowcase type cover.Tucking in the extra.The canvas is cheap and I get 2 purses done from one piece of canvas.(50cents)They are addictive but fun.Mary
