There is also The Back Door General Store in downtown Whitefish. It is a very small quilt shop and gift store. (Kill two birds with one stone?) They have a lot of McKenna Ryan's patterns and quilts, as she is a local! If you Google the store, you will find a map as to where they are.
And, there is Big Sky Quilts in Great Falls, and Creative Stitches and Prickly Pear in Helena. Again, just google them and print yourself out a little map, and you will be all set! Have Fun!
(My favorite is Glaciar Quilts at the north end of Kalispell, which Sherry already mentioned! It is right across 93 from Costco!)
