I did it ... yes, zig-zag tunnel back. I did mine on Minkey though so it almost disappeared.

I use a double needle to stitch in the ditch. I don't thread but one needle. The unthreaded one is to keep the stitch line perfect equal distance and straight.

Everyone is right. It really doesn't save time and it doesn't look very professional from the back.

I did a double needle on either side of the seam of a denim quilt. Just squares, and looked so much better than the rag quilts. You have to really drive slow.

What a clever idea!!!

Not a time saver, but you can do some faux quilting-- just the pieced top and the batting and maybe a stabilizer to keep it from tunneling-- with the double needle, then add the backing and additional quilting to keep the whole sandwich together. The only advantage is that you have perfectly parallel lines for focal points.

I've spoken a quilting friend who used it on a sampler quilt. She liked it very much

I use my presser foot for a guide to have two lines of stitching close together. Since I want the same look on the back I use a single needle and stitch two rows. Yes it takes more time but I'm not in a race so it doesn't matter to me. I am frequently asked by people who see my quilting if I used a double needle.

I was thinking this would be a great method to use for a stained glass quilt. The black strip that looks like leading needs to be sewn on both edges and maybe a double needle would enable me to sew both edges at once. I would definitely follow RST suggestion to sew all the leading before putting on the backing and quilting the rest of the quilt. Thanks for that idea!

I use a double needle to hem Tshirts and pants that are stretchy because the stitching will stretch and not break. It doesn't look good on the back side and I would never use it to quilt a quilt. Sharonve
