Because get this - not only did I use the specified yarn for a pattern, I even used the specified color. I think this might be the only time I have EVER used the called for yarn, which could explain why I run into gauge problems so frequently. Although maybe using KP shine sport for Picovoli counts, since that was one of the suggested subs.
Of course, this using of the specified yarn was a total coincidence. I had 2 skeins of Filatura di Crosa 127 Print sitting around for a year, and then the Winter Knitty came out with the Calorimetry pattern in it in the same color as I had bought. I don't think I would have looked twice at that pattern otherwise, but when I saw it I thought, hey, I have that yarn! Here it is:
This pattern is really cute and creative, but as many people in the blogworld have noted, the instructions as written will make a really gigantic headwrap. I'm so glad I have the internet community to do my work for me! I used size 7 needles instead of the called-for size 8, cast on 90 stitches instead of 120, and knit 24 rows instead of 40. I think it could stand to be even a little smaller, but it's not too big as is either. I only used 2/3 of 1 skein and I have another skein, so I can make a few more until it's just right!
Verdict - cute, comfy, and fast (took me a few hours, I'm sure actual fast knitters could churn it out in much less).
