I mark the first straight row with chalk, then decide on far apart I want my rows. I cut a piece of plastic straw to the size I want and slip it on my bar that came with my machine. That bar goes into the little hole on the foot and the screw in the back tightens to keep it in place. This allows the bar's foot to run along the previous first row of stitching so you can do the rest of the rows without measuring. The reason I put the little piece of straw on is if the screw loosens, I now right where the bar should be and I retighten the screw.
i start my first row of stitching in the center of the quilt and stitch out to the right. Once one half is done, I rotate the quilt and stitch the second half the same way.[ATTACH=CONFIG]606173[/ATTACH]
