Here's the latest bunch --
I got all inspired by the newest Sally Melville book (which might not count as new anymore, but I just found out that the library has a copy, so it's new to me) and the idea for about making your own varigated yarn by striping different yarns together. I'm pretty sure that just makes stripes (Dawn had a great idea to spit splice different colors of wool from a striped sweater she'd unravelled to make a yarn that really would be varigated, which I'm anxious to try someday when I've got a striped sweater and know how to spit splaice), but it's been lots of fun to play around with.
My favorite is the hat with the wide stripes. I used the varigated yarn and a solid yarn in the same shade of dark blue and worked four rounds of each. The dark blue matches the one in the varigated yarn closely enough that the two stripes blend together and hide the straight lines that make them look like stripes. I want to do a whole sweater this way.
My other favorite thing about this is that if I was knitting hats for my own kids, I could get at least four different color combinations with two skeins of yarn. I have a hard time starting a baby hat with a brand new skein of yarn because I know I'll still have 3/4 of a skein left and it seems wasteful even if the yarn was cheap. I'm not claiming I would knit that many hats, but I like knowing that I could.
