There are several of these in my queue and favorites on Ravelry. The top of these (the one I'd most like to complete), is the Celestarium shawl, by Audry Nicklin. The nerd in me cannot help but adore this. It's been well talked about on various podcasts, but in case you haven't heard of it, the Celestarium is, "...an accurate view of the night sky from the North Pole in the form of a pi shawl." I cannot fully express how much I adore this. However, there are several reasons this is on my Holy Grail project list, and I'm afraid to knit it. First, there are beads (to represent stars) and I haven't ever dealt with beads before. They seem like they could potentially be a nuisance. Second, this thing is huge.
