I put my thread in plastic storage boxes made for scrapbook papers/supplies. I get them when they go on sale at the local craft store. If they're on sale I only pay $7 vs $15 or $20. They stack nicely and have a carry handle too, but I don't usually carry them anywhere. They are 3" deep so all thread except those on large spools fit. I use a tote box for those large cones. Make sure you keep your thread and fabric out of the sun. Whenever I'm going to rearrange a room, I make a scale drawing of the room and all the furniture, ironing board/table, stacked totes, boxes, etc. Use graph paper and make cut outs of the furniture. Locate windows, doors, etc. within the room. It's much easier to move around little pieces of paper than the actual furniture. Make sure to allow walking space between and around things. As for your design wall, flannel or fleece works well too. Good luck!
