Vestvember yarn

Hm - this pic really doesn't capture the colors at ALL, especially the purple. Anyway, this is Colinette Jitterbug in Vincent's Apron (the yellow) and Velvet Bilberry (which is actually a very bright, royal purple). The idea is to knit a fitted v-neck vest with corrugated-ribbed trim in the purple. But now I'm not sure I want to do that. I'm feeling a tad shy now that the yarn's right in front of me. I'm going to whip up a swatch and see how I feel. (Literally - I'm being slowed down this Vestvember by a cranky right shoulder/arm, very annoying.)
