I have 10 machines now, probably 12 by the end of the week. Each one is useful to me for a variety of reasons. Some I use just for the cuteness factor! I can't tell you how many people comment about my cute, pink vintage Morse, or my adorable Singer 185K.... Really, it's all about having fun while sewing and if using unique or sweet "tools" makes you happy, like it does me...the more machines the merrier. I do think I'm about done with 12 machines though!
