I am making saucepan holders and have pinned the material so that it does not pucker when I sew but it does anyway....so tried sewing without the safety pins... still the same... I have sewn one way and then the opposite way... still no joy... no use sewing curvey lines as the same thing would happen... there must be an answer as the bought pot holders are not like that... !!! This is the quilting on them I am talking about. I will never be a quilter at this rate... thank goodness I am am not.
