I'm working on a top-down seamless sweater and have made it to the ribbing at the waist. I now can see that it is about 2 to 3 inches smaller than I'd like around the chest. (Cut me some slack, it's my first seamless) It has a fair isle pattern circling the chest and back that has a good stretch to it. Would you rip out and rework it, or would you block it first and see if you could pick up the extra inches without starting again? I would usually rip it out, but I'm leaning toward blocking this time because (i) it has such a good stretch and (ii) I realized it is 21,840 stitches from the start of the fair island pattern to the ribbing. Yikes!!
