I also used to have lots of issues with puckers/tucks when I FMQ'd my quilts. At that point, I was just pinning my sandwich together. Then I bravely bought an expensive can of spray and things will never be the same. I LOVE the adhesive spray. I spend a bit more time, smoothing the top and bottom but once I'm finished with that...FMQ'ing is a breeze. I move it all around, fold it up, put it aside for other projects...and the fabric don't move and wrinkle. Best product ever!! Now I just panic if I'm down to my last can!
