We lived in Anchorage for 14yrs and we loved it. You are going during the cold winter months. Dress very warm and bring boots depending on what activities you plan on doing. If you are lucky you will see moose and maybe a bear. It is a beautiful state.
There were not many quilt shops when we were there but that may have changed. Google will help you with that. Order a copy of The Milepost magazine before you go if you can. It will have information too. Have fun.
