Do you have access to the new house to measure your space? When I moved my sewing room into one of my older son's old rooms, I measured every wall, the opening of the closet, the depth of the walls of the closet, the height to the window, the height and width of the window, everything! Then I measured all of my bookshelf dimensions, the sewing table, ironing board, cutting table, even the sewing chair. Next, I drew the space to scale on graph paper. I also drew out all the furniture to scale and then cut it out. That let me play with placement to know what I wanted where. I also checked out a few books on organizing your sewing/crafting space. I got lots of good ideas there, too.
