I am a new quilter. My greatest difficulty has been in marking the quilt. I followed directions which stated to mark after sandwiching and basting. I have a great kitchen island on which to work. But, when I mark a grid on my muslin squares to offset the applique, the muslim "moves" or "stretches" making the marking difficult (sandwich flat on counter top). I do not know what the problem is - if it is poor quality muslim, the marking instrument (erasable quilting pencil), my method or "par for the course". Suggestions would be greatly appreciated.
