I'm almost to the point of quilting a queen size quilt (my first big quilt!) and what I want to do is stitch-in-the-ditch and then sew lines 1.5 inches from the seams. I have a Juki TL2010Q that came with a walking foot, but it doesn't have a guide. I'm thinking that having a guide will alleviate the need for marking. I have seen that Juki has an adjustable edge guide foot, but would I have trouble with puckers on the back given that it isn't a walking foot? Any suggestions on the best way to do this? Thanks for any help you can give me!
