I have found for myself that working from the outside to the inside works best - I haven't run into any trouble yet and have done up to a generous queen size this way. As soon as I have the first outside done, I cut off all the excess backing and batting to cut down on the weight. I have switched to Hobbs 80/20 batting also to cut down on the weight. I use gloves and I spray baste! * I always pratice first on a square*
