Thanks to Aunty Em's suggestion to me about knitting in the round, I bought myself two sets of DPN's, watched Amy's video, and gave it a go!
The yellow cap I made (above) was knitted with worsted weight acrylic on sizes 8 and 10 straight needles. The one I'm making now is with sport weight acrylic on sizes 7 and 8 DPN's (the pattern called for size 6 and 8 DPN's, but I couldn't find any size 6's and I knit kinda tightly anyway, so I figure it should still work). Anyway, I'm only about 3/4 an inch into the ribbing, but I've noticed that the circumference looks a lot smaller than my yellow cap! I mean, this cap is looking pretty tiny so far. Will it get bigger the more knitting I complete? Or does it just look smaller because the yarn is sport weight? Is it because the needles are smaller? The pattern calls for casting on 48 stitches with sport weight vs. 44 stitches with worsted weight (on bigger needles)...so shouldn't the size of the cap still be the same?
Thanks in advance for any help you can give me! This in-the-round knitting is pretty challenging, but lots of fun!
