As far as the pattern, I didn't really follow one, because I just can't, lol. I can't find the link for the one I based it on, but I think I just did a search here on Craftster for "crochet calorimetry" and found a few. Then just winged it...I think I started with a chain of 5 and then increased one stitch every other row, until it got wide enough, then kept it the same (no increase) for about 10-12 rows, and then started decreasing every other row. But I didn't keep good enough track and it got all wonky. I am making another one now and am paying much more close attention, and so far, it is looking a lot better.
