Rock towers (dacite)
Arizona Barrel Cactus (Ferocactus wislizeni)
I grabbed the single skein of Silk Garden on my way out the door, cast on during the drive there, knit a bit during lunch and dinner, knit in the dark on the drive home, and nearly finished it in one day.
Whenever I have a new pattern (especially because I usually design with indie or organic yarns, which can feel inaccessible for some people) I try to also show it knit up in a more readily-available commercial yarn. I had one skein of Silk Garden sitting on my desk, and it was perfect.
