I'm quilting a queen sized Lone Star on my DSM. I heavily starched the backing & starched the top as I pieced it, which helps prevent any puckers or pleats. Then I marked it & pinned, pinned & pinned. I have over 957 2 inch safety pins in it. I use my ironing board to help support it as I go. I'm also doing Machine embroidery on it. The last one I did I messed up one embroidery design & it took me all day to pick it out. I look at mistakes as learning sessions
. It also proves we are not perfect, nor are our quilts.
