My Singer CE-250 is set up for embroidery only (never tried sewing on it). My Singer 9940 is set up with black thread right now for a WIP, My White Speedylock 639 for serging.My 301 is set up with beige thread for a WIP, my handcrank 128 is set up for scrappy piecing. The other machines are in various nooks and crannies around the house awaiting a project. I like having each machine set up for a different project so that when I tire of one project I can just switch to the other one quickly.
