Sleeve On

I'm frustrated with my Oriole vest. I'm using the two-handed method of fair isle that I learned from Philosopher's Wool, and that's working fine - even though I'm working back and forth because the vest has a solid back so is not in the round. The problem is that I seem to have "ridges" in the knitting. Every other stitch appears to be a raised row, creating vertical lines. I can't figure out what's wrong - unless it's somehow related to my two-handed purling technique.

I was out looking for some insight into what's wrong, because I'm thinking it must be a tension issue. (Geez, I can't imagine having to frog this and start over again!)

I ended up looking at Wendy's site and found some discussion of floating versus weaving. Maybe I should give floating a try. I just don't know how to do that two-handed and I hate have to drop the yarn each time and then deal with the tangled mess of yarns I end up with. Can someone help!?!?!

At any rate, I'm really disheartened by how it looks up close.

So, last night I picked up the Cascade Skye cardigan and cast on the second sleeve and did a few rows of that to get it going so that it's ready to be picked up and knitted on whenever I've got a minute.

Here are a few pics of the finished sleeve close-up:

   

The thicker yarn at the cuff is Apollo from Colinette.
