Let's start off with an awesome example of arts and crafts, unlike most of the junk on Etsy.
Unfortunately, everything on Etsy doesn't have the creative gall, the raw aptitude for awesome, and brilliant craftsmanship that this squirrel riding a snake has. Fortunately, there is a certain art and craft to making truly horrible things, so while these crafts are unambiguous fails, Thomas Edison comes to mind stating "I have not failed. I've just found 10,000 ways that won't work."
Indeed, these Etsy creators have done the same, except their failures are online so we can laugh at them. For example...
