There are many many patterns out there on the Internet and this is just a small selection. I will keep updating this list so please do let me know of any other links.
Let's start with basic tutorials courtesy of PlanetJune here. Including an excellent one for making a magic ring here.
If I am making prizes for the children I want something small and quick to make. Here are some I have find (or been directed to by wonderful helpful people):
Little Yoda by Happy Together
Tiny Whale by PlanetJune
The tiny whale is donationware. Now I know there are lots of free patterns available but I am always happily willing to pay for lovely patterns.
So here are a few shops:
Stripey Blue on etsy.
PlanetJune (has such lovely animals).
