I wouldn't get the same gauge now as I did then regardless. I've finally managed to teach myself how NOT to garrotte the needle... most of the time at least. But anyway.
What I was really getting at was Jan was using US 7s and worsted yarn and I was US 9 and bulky yarn and we were getting about the same number of stitches and probably
working on about
the same size hat. For Wendy (who's a very relaxed knitter) to match my gauge she'd have to drop at least 2, maybe 3 needle sizes from what I use given the same yarn. (And it used to be more like four
I've also had at least one occasion where two yarns that were only slightly
different (Plymouth Select and Cascade 220) gave me just enough difference in gauge that the same pattern fit in one yarn and not the other. And this wasn't just on the same size
needles, it was the same actual
needles. The Plymouth was springier and slightly thicker, and fit perfectly. The Cascade was just slightly
thinner and came out too big. Not by much, but enough that we had to do some fidgie-widginess to draw it in a little. The lesson learned: Take Time To Save Time; ALWAYS Check Gauge! Maybe Mercury was in retrograde or something so it was a one-off, but...
