I have the same problem. For awhile we had 3 places but we are now down to two. I have a machine and cutting mats, rulers, etc in both homes. What works for me is this: I go through my patterns, quilt books etc. and I put together kits These I take to my second home. If you start moving your stash into your smaller house you will run out of space. It sounds like you have a beautiful space in your mountain house and room for your stash. I'd keep things simple.
