I love this process. I use the preprinted interfacing that's already gridded. This is great from preparing scrappy blocks. I even use hst with this gridded system. It's amazing how easy they are to work with once ironed to the stablizer. It gets all my scrapps used up and makes transporting them easy. These make great takke-a-longs for retreats when you need to sew but don't want to pin and stress over matching seams. It a great relaxer for retreats or any time.
