I am pretty new here, but have been admiring all the Bow Tucks purses for quite a while now, and would love to make one. Before I order the pattern, I would like to know if you use regular quilting cotton, or a heavier fabric. Also, what kind of batting or interfacing.........fusible or something else, and what weight ? Also, do you do any quilting after you apply the batting? Thanks ahead for your help.
