I bought Velcro tape with one side sew on and one side stick on. I put the adhesive part on the wall at the top. I sewed the sew on part to a huge piece of fleece fabric - not the anti-pill. It holds everything except a sewn together quilt. I never pin blocks or rows or columns. The only thing that will remove a few blocks is a certain Border Collie's tail. The advantage? Easily removed for holiday dinners and quickly replaced - it's in my family room, so I prefer to have the wall uncovered when I have a lot of company.
