I've been there a few times and bought several yards of fabric. At our last port of call, I load all of my treasures into a tote bag and head straight to the post office to shove it all into a flat rate shipping box to send home! Skagway really needs to open a post office closer to the quilt shop instead of way past the Red Onion Saloon.
They do have a great selection of fabrics on their website too!
