Etsy seller CraftyHedgehog's knitting project is a blast from the (high school biology) past: a frog dissection, with a hand-knit frog and needle-felted innards!
And as a touched of added realism, the piece isn't glued down - instead, it's pinned to the board, just like how you did it way back when ... but minus the icky grossness.
Etsy is pretty cool. I did all my christmas shopping there. Its kinda neat to think your money is going straight to the artist, instead of the exec at some large corporation.
