Via Karen’s Wild Coast of Bohemia blog:
Cake Wrecks where all bad cakes go to die (some of those turkey cakes are burned into my retinas)
Craftastrophe “because handmade isn’t always pretty”
In a similar vein, one of my favourite sites was You Knit What?, which was a blog devoted all things horrible in the knitting pattern world. Too bad they abandoned it a couple of years ago, but the archives are still a fun read.
