I admire you for what you've done in wanting to rip and start over. I too have a Juki 2010 and am determined to learn. There's just something about quilting that isn't so perfect that appeals to me. My very large ones are still going to a long arm quilter, but I want to be able to do all the smaller ones myself. I am getting better so I figure that is the benchmark. Good luck to you.
There is a video on You Tube that shows sandwiching on an ironing board that I thought looked doable.
