Because friends don't let friends knit fug.
I am officially booting the idea of the pants. Some of my reasons are yours, namely the sag factor. While I appreciate a great pair of lounging pants, I can't imagine spending that much time knitting a pair, nor the amount of money that the Koigu cost at the time that I purchased it. Of course, I would have no problem making socks out of all of it :)
I should make a shawl or a throw I think. I'm just not sure I am a "shawl person." And I'd like to do something for myself. Though, I am usually much more motivated to knit for other people. I was looking the Charlotte's Web Shawl. Very beautiful, but enormous project. And the Clapotis looks incredibly challenging but I'm sure I could get through it if I really wanted to. The problem is the volume of Koigu. We're talking many and varied projects here unless I do something big like the shawl. I did a Koigu headscarf last year that came out really lovely. But, talk about sag, I should never have even brought the pants up now that I think about the drape of that scarf.
And just so we can all drool together, here is the stash of Koigu. Isn't it lovely? The top photo is with flash and the bottom without, just to try to get to true color representation, I thought I would share both.
