Thank you to all of you who responded to my what should I do about these pants. You were all right, they look cute I think!
Yarn: Noro Kureyon 132 and black Lamb's Pride
It was a bit of a pain in the ass to get the legs to match all the way down. I pulled out 2 small balls and started in the same place, but toward the end, after the red, the purple stripe wa a lot bigger on 1 side than the other, and the place where the black stripes started would have been purple without any green, (that ball barely had any green on it at all) So I frogged back and took out some of the purple stripe, and then grafted some green from somewhere else in the yarn to get it to match there.
Here's the back. You can see one set of short rows fall between the black stripes, but I think it works well. They've gotta go somewhere!
I *really* like how these came out.
