I think if you post them directly into the tutorials section, whoever subscribes to the vintage machine part of the board will see it. I see things from main, pics, general, tutes and links in there all the time. Perhaps there wouldn't be a need specifically to move it anywhere if it starts in tutes. I'm sure you're correct and it's something to discuss with a moderator.
I'm certainly excited. I didnt' think I'd ever have a need for the ruffler or hemmer or anything else clothes-wise, since I only make quilts. Then I came across one of Craftybears great sites and am making my first shirt for myself EVER! It needs ruffles, but I doubt I'll use the attachments just yet.
