Actually, I sewed all around on all 3 of them --but, understand the strips for the borders were cut already. They were wof so I joined when needed re length. Each plain border got wider. I cut at top or end of width so no miter ends.
This was on a printed panel about 48"x60" but it will be longarmed as the group owns one.
Surprisingly , came out with NO ripples but I did not stretch.
these are charity quilts for canceer patients but we make them according to correct quilting methods.
For some reason the method just slipped my mind.
