I just have to ask . . . why do some of you have so many sewing machines? Do they each do something special or better than the other? I'm saving up for a stand alone embroidery machine and maybe someday a Bailey's, and could see me trading up to a bigger/better sewing machine - but can't imagine why I would ever need/want a 2nd? Or is that something to look forward to happening after a few years?!?! (I'm new to the hobby)
