i am locked in a battle to the death with my wow machine. it's winning.
the wow is a sewing machine whose neck has been stretched to allow you to get a big quilt under it easily. in theory, it's a big improvement over other home sewing machines, especially in conjunction with systems like the handiquilter or the superquilter. in theory, it allows you to stitch bigger patterns with a greater range of motion than a traditional sewing machine allows.
these machines are heavily in demand, because so far there's no good alternative for home machine quilters (though i'm hearing there's one on the horizon from the people at handiquilter -- i am heartsick that i didn't wait). i got it in november, after being on the waiting list for eight months. i expected a learning curve, and after ruining two charity quilt tops on it, i resigned myself to spending several more months mastering the machine.
it's taken some tinkering. most recently, the machine wasn't forming stitches at all, so i had to lower the needle bar, which hadn't been plunging deeply enough to let the needle enter the bobbin case properly. that fix seemed to work.
however, now the problem i'm seeing is even stranger, and still has to do with stitch quality. i can get the machine to make very nice stitches in two directions (toward me and from left to right, both from the needle end of the machine). the stitch quality goes promptly to hell, though, when i push the machine away from me or try to move it right to left.
operator error, you'd think, right? my first thought was that i was moving the machine faster in certain directions than in others, but when paul watched me he furrowed his brow and said, "i don't think it's that. you're moving like a robot."
i'm taking a machine quilting class at quilt university, and the suggestion i got when i asked about this was to try rethreading. i will try it again, and a new needle, and cleaning out the bobbin case, and sacrificing a goat, and reading the entrails of the chickadee currently on the bird feeder.
