I have made many quilts and machine quilted them. I decided last week to straight stitch 7 quilt 45x60". The D9P puckered really bad in some areas, I just kept going thinking it would get better it didn't. I was ready to sew on binding. I decided I could not live with it. I have spent several hours the last two days unquilting I will have a couple hours tomorrow to finish it. Then I will FMQ it and that is my usual quilting method. I should stick with that. I was trying my best to do it nicely, I must have stretched it or squares were cut wrong. I will donate these quilts but want to be proud of my work. Good luck on your quilting adventure.
