I just noticed Marney's comment below, and had to respond because I wasn't that clear when I posted yesterday. I am not worried that the bridesmaid tops will be see-through. I'm worried because the person at the store commented on the thinness of the yarn and now I am afraid it will take longer than I expect to knit the tops and I won't finish them on time. Yeah yeah, I know - if I start now it definitely won't be a problem. Bleah.
