Are you retired ? if not then just take projects with all the needs for that project (s) to the other house . Reason I asked if you are retired if you are then you will probably spend more time at the fishing shack LOL cute name than your own residence during spring, summer and fall ... Then you need to take it all to the fishing shack, otherwise its just projects to be done ...
But then to me ... I would use whatever has the most storage and room for most of the main sewing, quilting, crafting.
