Probably the best way to do this (if your closet is big enough) is to spend one (or two) days boxing up all the stuff you don't need *right this minute* and putting it in the closet. You're going to need to make some choices about which things you want to have out, and which things can be stored and pulled out. Can't tell from here, but you might be able to fit your sewing machine table between your dresser and the door or under the window.
Will your brother let you store anything at all in his room? Depending on how long he's staying, and how much stuff he's moving back, he may have some extra space in his room. Of course, if he has a whole apartment of furniture that he's trying to move in (like my sister did when she moved back in), it's not going to be pretty.
Well right now, every nook and cranny of bedroom is just full of stuff, including my closet. I was thinking I could just do like they do on TLC's Clean Sweep. Where they just take everything out of the rooms and sort into "keep", "toss" and "sell" piles. That way I can just get rid of stuff I don't need right then and there. And then while everything is out of my room, I'll prolly paint it. Yeah I intended to put my sewing machine table right underneath my window so I could open the window on a nice day and have a breeze coming through. I just have to think where I'm going to store all of my fabric. I have a MASSIVE amount of fabric in storage right now that needs to be sorted through.
My brother isn't a materialistic person so he won't be moving a lot of stuff back but I don't want to have to ask him if I can store stuff in his room because I don't want to have that much stuff, ya know?
