Nice quilt Aces. SID stands for Stitch-In-the-Ditch. If you go up to Search at the top of the page & type in whatever you're looking for, it should come up. I just did that & it brings up lots of posts on SID. FMQ is free motion quilting & you'll figure some of these out on your own soon, or you'll read them on current posts. It's a great place to learn while you practice. My problem is I want to do all of them & don't get many done for looking...LOL.
