In spite of my extensive pin collection, I use glue fairly often. I spray baste all my sandwiches and have tried the Elmer's in a glue roller once. I may try again. I use school glue on seams that are on the bias especially if they are smaller pieces. I also have a stick of 505 temporary glue and use it on seams.
Glue and pins galore and STILL not everything lines up perfectly all the time.
