I have basted blocks together, those with multiple seams and also PPed blocks where there is a lot of bias edges. Sometimes that extra care makes or breaks a pattern. With all the work that goes into building a quilt and if you really like those perfect intersections then basting or gluing or pinning all work towards that goal.
What ever works for you is what you want to do.
I want to try the glue. I watched S. shambers video on how to do it and looks like a good tip.
