i have never had a problem before but now i can't seem to get my machine to work on the touchtape. i wish i knew what kind of needles i was using. d'oh. i opened a new package today and they're schmetz "jersey ball point". it says 130/705 H SUK, and of course i have no clue what that means. i think there are 3 different sizes in the package (70/10, 80/12, 90/14 -- don't know what that means either, but think the second # refers to thickness of the needle?) and none of them work on the touchtape. they all skip stitches on the tt but not on fabric. so, i'm wondering if i need a different size or if i need universals...
