I didn't use to starch at all, but after taking a quilting class this summer the instructor suggested we try starching our fabric before cutting and piecing on one of our next projects to see if it made a difference. Although I was only constructing a small Warm Wishes for a baby blanket I thought I would give it a whirl. I used Best Press (because that's what I had on hand)...voila! It made a noticeable difference, especially in my piecing and joining the WOF strips.
