SWS felts in a HURRY. I timed it, and in a bit over three minutes, the bag was felted, tightly so. Not a stitch defined, anywhere. My hot water is pretty hot, but I can still fish the pillow case out bare-handed, so I think it's the yarn, I really do. I'm almost tempted to felt it on the delicate cycle next time, just because this way requires constant vigilance!
This is the Sophie pattern, basically. I'm calling it the Not-So Sophie, because I like a shallow, barely bigger than my wallet bag that fits snugly under my arm, on my shoulder. I dropped about 12 rounds, so I decreased at 10, 20, 30, 35 and 40 rounds, and bound off after round 42. It took right at two balls of SWS, or 2oo+ yards. The colorway is Natural Navy, done on #10.5 circs, with the same sized dpns for the i-cord.
I felt in a polyester, king-size pillow case, tied shut, with four of Mugsy's tennis balls thrown in to beat it up a bit. I add about two tablespoons of soap powder and wash on hot/cold. Then, with the Knight's help, I stretch and pull it into the shape of choice. Anything in the house can serve as the "form" during the drying phase. If it fits into the bag and looks approximately like what I want in the end, it's called into action.
I also took this shot for you. SWS is a great yarn for felting, but because of this very trait, I can't imagine using it for non-felted items. A pal made me a sock bag in SWS - unfelted - and I think I might line it for future use. The early fall edition of Creative Knitting has a cardigan/jacket done in SWS on the cover. No way. It would pill and shed too badly for practical wear, I'm certain! I didn't do anything but hold that bag in my lap while knitting away on it, and you can see how fuzzy the bottom is, and how that one "blonde" strand pulled itself loose. Of course, thanks to the nature of felting, the finished product reveals none of these little secrets, and is rock solid, tough and ready for my daily use.
I don't get the names Patons uses for SWS colorways. There's no navy in this wad of color. Purple (gasp! it's true!), lots of tan and taupe that thankfully turned a solid, warm brown, a touch of grey, and the black in the unfelted version just felted into a dark grey. Still, even with the purple, I'm very pleased with the results. It's a bit deeper than my summer Sidekick, and it won't show dirt. Perfect.
