The 'blossoms by the brook' shawl is growing. If fact it's gotten a little overgrown. I followed the pattern until the last few rows and realized I had a lot more yarn left. So I unraveled the top 10 or so rows of decreases and added in some more repeats. It really, really hurt to watch those long, long rows getting undone, but I decided I'd rather that than have a lot of unused yarn.
I'm pretty sure there's enough yarn to finish. Unfortunately, pretty sure is not the same as absolutely sure. Ah well, when in doubt, knit faster.
