I've probably cranked it down a little too tight if this is happening... See how the teeth of the ratchet things are a little chipped down? I need my husband to be my machinist and fix them for me. He'll do it.
I've been getting a few customer and guild quilts that have been needing some fullness worked in. Sometimes if you crank it very tight it works out. Other times I have to put my hand in there and work around the fullness. Either way... It has to be dealt with.
