I'm still working on other projects so I haven't even swatched yet, something I will do so I can see if it works right for the pattern I choose. It'll also tell me if it's tolerant to frogging, if not then I probably won't make as many swatches. I do hate swatching though, but then again most people do.
I guess I'll start on the process, swatching, pattern selection, knitting, in about a week or two.
As for metal detectors, well the wire's thin but I guess that a large item would probably trip it. I just guess that whoever receives the item (if it's good enough to gift) can't take it to court or on airplanes.
