I, too, cut my binding at 2.25" almost exclusively. However, I'll be cutting and attaching binding on a large bed quilt for MIL and may go with 2.5" or 3" for it. It's a hexagon quilt made totally by hand by her grandmother in the 1930's. It was quilted by hand, but never got the binding made or attached. I want to try to find fabric that looks good with those in the quilt, but haven't found any yet. Today's colors are totally different I haven't really looked around yet much, though, so maybe after the holidays I'll do that.
