Ok, so I've gotten the pinky finger done on the Birthday Gloves.
1) This pattern requires -a lot- of math to make it work. Not necessarily hard math, but it's just making sure that things line up right and work right.
The pattern expected that I would do the pinky finger on 4 needles, 18 stitches on the needles. That just seemed too finicky, so I went down to 3 needles. Unfortunately, all of the pattern dicrections for the decreases at the top of the needle are written as "k2tog, k to end of needle, ssk." So I had to do the math to figure out where the decreases were supposed to go on my 3 needles.
To make matter worse, you do the decrease round twice, with the same description. But on the second decrease round, it doesn't make sense. After the first decrease round you have 8 stitches decreased, (and 10 on the needles). Ok, fine. But 10 stitches won't give you 4 stitches per needle on 4 needles, so you can't do both k2tog and ssk on the same needle. Three needles would have three stitches, and one needle would have 4 stitches.
I just ended up doing it as (k2tog, ssk) repeat to end, and it seems to have turned out ok.
2) I think I'm going to do the thumb next. Because it's an afterthought thumb (which I've never done before but it doesn't look too hard) I can do it whenever I want. The reason for this is simply that it should make it a lot easier to try them on for rough sizing or to get pictures (my giftee's hands are only a little bit bigger then mine.)
Despite all the trouble, I am -really- liking the pattern, and I do plan to make a second pair (for myself!)
