Okay, this cardigan is very relaxing to knit. It's been in hibernation for a good, long while though. By the time I took it out of hibernation, the pattern had been updated numerous times, making the sizes smaller. And I can see why. I tried the cardi on while working on this right sleeve and it's HUGE. And I even got gauge! I decided to look at others' cardis from about the time I bought the pattern and several remark that the cardigan is large. Also, I used a merino which seems to be growing as I knit - I think the pure stress of holding the cardigan the way I am holding it in order to knit the sleeves, is stretching it a bit. Now I'm a bigger gal - I wear a size XL - but this sweater is probably an XXL in size. (I like to think of myself as fluffy.) So, while I am unwilling to frog the project, I know it won't fit as intended. And that's okay. The pure experience of knitting my first sweater is terrific. Also, I think it'll be a very oversized, comfy cardi to curl up in while reading this winter. So, it's not like it's not functional. AND, I think I paid an entire $40 for the yarn (and I'll have quite a bit left over), so that's another reason not to frog. If I had used Mad Tosh or Wollmeise or even Malabrigo, I would have probably repurposed the yarn for something else. But since it's KnitPicks Stroll (a very inexpensive, though pretty yarn), I'm less inclined to frog.
Chalk this one up to: You live and learn. :) I'll finish the sleeves (which seem to be the largest fitting part of the garment on me), and then pick up the collar stitches. I actually really like the casual look of the rolled collar, so I'll probably knit it in stockinette stitch as indicated in the pattern. I know some people matched the collar to the sleeves and bottom rib so that the collar didn't roll for them. But I love the loose, open cardigans with the relaxed, rolling collar right now - and since the whole sweater will look VERY RELAXED (maybe I can shrink it a bit w/o shrinking it too much), I think it will fit the cardi well.
