I'd like to make this
shawl, but I have a question about what size needles.
First--about the needles. The pattern states that you are to use a worsted weight yarn, but use size 13 needles. Now since this is a vintage pattern, do they really
mean size 13 (that is, 9mm), or do they mean something else? Worsted weight yarn typicaly uses somewhere between sizes 7-9 (4.5-5.5mm) needles, though I realize that the size needle will need to be bigger because the shawl's fabric must be drapey.
Okay, now what about the gauge? They're telling you to cast on 100 stitches, so will this work out to be the right width (the 19")?
