I know your head is spinning! It is very frustrating and messy. Im doing the same thing right now, only I thought I was downsizing. After cleaning things out, keeping what I would use, and finally getting organized, I have more room than what I thought. I even have more room for new fabric, WAHOO! For years I would rip pictures out of mags. or patterns and stash them in the plastic sleeves, I have 4 3ring binders full, think about how many mags. that was! They all got recycled.I also agree with the idea of a mini frige and coffee maker. I have them in my sewing room.This way, if im really into a project, I dont have to leave, and the bathroom is right next door.
I have been to the UP and I love it there, it is beautiful! Good luck with your room! :D
