hi, im new to quilting, ive up until now only used my straight stitch, ive got a hardly used singer simple 3116 sewing machine. ive gone over the sewing machine book. my fancy stitches wont work period. ive got some awesome crazy hearts i wanted to zigzag onto blocks for valentines day. the manuel says to just turn the knob to the coresponding design you want and start sewing. anybody else have this problem or know how i can fix it, im good at fixing things.
