I only do hand quilting and though I have tried a hoop or frame, I end up not using them. I find if I baste enough, I can keep it flat. I keep it on my lap and check frequently as I quilt. Only once, recently, have I had to undo and re-quilt and it was only a foot or so and I really could have let it go.
I quilt in front of the TV but have other projects going on so I really have no clue how long it takes.
I am currently working on a big quilt-extra queen size-and am making great progress: 4 of the 12 squares mostly done, including their sashes. Sometimes I go back and add more when I see the overall look.
At my current pace, I anticipate being done some time in September! No kidding. It takes me a long time because I only quilt an hour or two at a time before something interferes. So a square a week or 6 hours times 12 squares = 72 hours + borders.
So this isn't very helpful is it! And it may not be accurate. It sounds like way too much time, but I am including marking the fabric, too.
