I was the one who started the previous thread on how to make a crescent shape. What I ended up doing was to use a combination of short rows and decreasing. When doing the short rows, instead of wrapping and turning, I just turned without wrapping, and then when long rowing back, I knit* the stitch that would've been wrapped together with the next stitch -- by doing this, you get a decrease and get rid of the short row gap at the same time. Between the decreases and short rows, you should get something that comes out like a crescent. You'll have to play around with the number of stitches to cast on and the frequency of your short rows/decreases to get the shape you want. HTH
I did k2tog on one side and (I think) SSK on the other side to get symmetrical decreases.
There is no right way to knit; there is no wrong way to knit. So if anybody kindly tells you that what you are doing is "wrong," don't take umbrage; they mean well. Smile submissively, and listen, keeping your disagreement on an entirely mental level. They may be right, in this particular case, and even if not, they may drop off pieces of information which will come in very handy if you file them away carefully in your brain for future reference.
