My gauge was 4 stitches to the inch before blocking.
I used about 3 and 3/4 skeins. It turned out much larger than I had in mind, but is a wonderful shawl to wrap up in. I didn’t realize this was worsted weight yarn until I read the label after finishing. I thought I was knitting with DK. I wondered why mine seemed so much bigger and was taking so long to get finished.
