I'm knitting the modular vest too. Just did a search on this board and that's how I found your post. How is your's going? Mine is coming along. I'd like to know if I should plan to block it, and if so, when will I do this. I'm working on the right front now and it says to not fasten off after the left front, I guess to go ahead and join at the shoulders (?). Anyway, with the collar and bottom border added later, I'm just not sure when to block or even if I should. Are you blocking it?
