The Binding thingy is on the top 10 gadgets list....Its easy, you are gauranteed a neat small already sewn corner. No unraveling because you trim close, I have been using this method for many years and it Never frayed, on baby quilts that are washed a lot- and on King quilts that are not washed so often. It actually takes less time to do than the traditional way....just in case ya wanted to know.. :-)
