Mr. printable has some great templates for snake finger puppets, both coloured and not coloured (so you can design your own pattern). We were excited to try this (my son picked this activity), but due to illness, we didn't finish up, so I don't have photos. Hopefully we will later this week. In the meantime, here is a link to the tutorial as well as printable templates. Image from mr. printable.
Update: we did make these — it's a good template. Here is our snake exploring the wall of a garage...Also, we did some vegetable printing for Valentines day. I don't have pictures of our finished valentines, we rushed them to school before I had the chance. We let them be pretty wonky and we had fun ·_·
