Same lesson learned again

I cast-on the Misti Alpaca worsted again last night. Only to have to rip it out again; this time because I twisted the additional stitches I had cast on for the front neck. So, I ripped it out yet again. Cast-on again and got about three rows into it when I changed my mind about the front neck shaping (I know, I'm fickle). I'm going to rip out these three rows and try again. Hopefully, the fourth time will be charm for me. One of these days I'm going to really learn that I shouldn't try to knit a sweater that I mentally envision when I'm tired. If the fourth go round doesn't work, remind me to find a pattern and line by line instructions!
