I have been able to purchase a Juki and a frame (FINALLY!) and am trying to work through the problems of being a newbie with it! :) I had a quilt on it - thought i was doing ok...but turns out there was too much bunching front and back. :(. I am certain I had it good and square - even the back... how do you go about squaring the top and the back before putting it on the frame? AND are the rails for the quilt after it's quilted (through the arm of the machine) and the one 'belly bar' is - are they supposed to be level with one another? Thanks.
