I love these socks. Begun January 4th, finished March 30th (technically 31st, I suppose). I bought the kit (by the Tsock Tsarina) in October at Rhinebeck, and they have been a joy.
I knit them partway together, but decided eventually that it was too much trouble to try to knit the roses into the fabric. They were ugly and stretched when the sock was stretched, and I needed some other method. So I knit the socks (top down, opposite from the pattern) with only the panels for the roses and not the roses themselves. Then, once both socks were finished, I duplicate stitched the roses on.
It worked perfectly!
