This is my first post on anything. I'm new to quilting, but not sewing. My son is leaving for college and I've been saving all of his sports t-shirts since he was 5. I'm making his Journey quilt. I backed every shirt on Pellon 906F and there is a 1 & 1/2 inch sashing around the shirts. It's all sewn together and ready for quilting. I have a new quilting machine and I've been practicing on a mock quilt. I've got the meander stitch down pretty good. I was originally going to meander just the shirts and do something different in the sashing, but I meandered across the sashing (on the mock quilt) and it looks nice also. So if I decide to do the entire quilt in meander, do I still stitch the ditch along the sashing first or do I forgo that whole ditch part? Will it be stable if I don't stitch the ditch? I'm so confused and my brain hurts from reading the entire internet and not finding an answer. Any input would be fantastic!!
