I just ordered a lime green variegated thread for the quilting, and I'm really excited to get started. Also figured out that my "Bubba" (Singer 31-15) wanted size 16 needles instead of 14, and he's no longer skipping sitches but doing fm quilting absolutely beautifully. Can't wait to try out that HUGE harp space. Also now set him up with a Singer Professional Walking Foot. not sure if I'll stitch the "Knots" part 'in the ditch', and fm the rest or what. Any suggestions out there?
