I would not consider Flying Geese a "must see" shop. It is ok but definitely not worth going out of your way to see. Goversville Sewing Center, OTH definitely is.
While a bit on the spendy side, Log Cabin fabrics in Ravena has a very nice selection.

there is also a 70 store shop hop going on in NYS thru September 2. Here is a comprehensive list of all the participating shops so this will help you plan stops.
