I have spent a lot of time over the last few days knitting swatches, trying to get gauge for the sweater I want to knit. The pattern calls for size 5, but I think I'm going with size 6 in order to get row gauge. If this sounds boring, it is. And frustrating. But I'm also practicing the drop-stitch ribbing pattern I'll be knitting the body and sleeves in, so it's not a complete loss.
I also discovered that the size 6 circular I have is 4 millimeters, while the size 6 DPNs are 4.25. I HAVE NO IDEA WHY THIS IS. I need to buy another circular for this pattern anyway, so I'll pick up DPNs that are the same size in millimeters.
