How old is your Juki? My TL2010Q is about 3 or 4 years old and the walking foot it came with was woeful...if you check the fb group for JukiTL2010Q owners you will find a lot of helpful information as many people have had similar frustrations with their walking foot and had them replaced for no cost. Having said that, it could be a combination of things as already discussed in previous posts. But above all...don't be so critical of your work....LOL, I never like any of my quilts while I am quilting them...it's not till they're finished and washed that I start to like them! Pop over to the fb group and have a read about.
