I think they turned out pretty great! I posted them on facebook and offered them to any engaged or married friends, and they found a home within just a few minutes. I think I'm even going to give him a bow tie before I send them to their new home.
I'd never crocheted this small before, and never with cotton yarn, so it took some practice getting them right. Of course I'm now obsessed with making all of the patterns in the book. I'm currently working on Nosferatu, who is adorable.
