I've been mooching around the Internet for crochet patterns, looking for things that might be fun to make as examples of things that can be done with crochet, for the sessions I am running in my stall. I've found some pretty blogs and motifs...
Both of these blogs have a bunch of tutorials, there's some good stuff;

And here are some of the single patterns I've found that I really liked;
and another hexagon
and a heart
I hope that these links are useful, I think I'm going to make a bunch tomorrow because I have tonsillitis again and a sofa day might help me to recover.
