What to do, what to do...

So, I was kinda on a yarn diet. Not really, like no one was watching me to make sure I wasn't buying yarn or anything, but...really...I have enough, like more than a years worth of things to do; knitting or crocheting or spinning. I just have enough. I realize that this is a bit like sacrilege but, really! How much hand-crafting can one person do? Buuuuuuut the Blue Moon is retiring some colors (might have picked up a few), aaaaaaaand Loopy Ewe had a shop update (might have gotten one little tiiiiiny skein) aaaaaaaaaaaaaaand I might have taken a trip to my local yarn shop, Tempe Yarn and Fiber and that would be where I fell down and my credit card cushioned my fall thus keeping me from having broken bones, which I totally appreciate but then again...

But I'm not sure what to do about it...
I want to make a cardigan...
I tried for the Sunrise Circle but there is just no way. Because, you know that thing about knitters that keeps them working on a project even though they know everything is wrong, and the sweater is going to be three feet too long and the sleeves would fit an elephant but they press on because they're already started and they've come so far that they can't stop now...well, this is the place riiiiiight before that. I swatched, no go. I went up a needle size, I swatched again. Dudes, I'm not getting row or stitch gauge. Not even close. But it's sooooooo frickin' soft. I keep thinking that I've been knitting long enough that I can just Make a Damn Sweater. Measure my favorite shirt, calculate the inches, figure in gauge and just make the thing. But, I don't wanna do math and I don't want to think. So, if you have some thoughts about a plain, no frills, maybe not even any shaping cardigan that would work with a worsted weight, baby-alpaca (with an amazing drape), let me know.
