Nope, there is no mistake. I just finished the first sampler afghan on Christmas day and now I started a second one. This one is also a sampler. Surprisingly, I love making afghan ... especially when I am knitting on the sofa, which is now covered with my first project. I can feel the satisfying feeling that something I made myself is being really useful ... much more so than wearable projects. The sweater I made I've only worn for a few times.
I've been reading some afghan-knit-along blogs and I am amazed at how beautiful some are. I am brewing the idea of the Great American Afghan.
