I completed an amigurumi panda, learnt the half-double crochet (love it), learnt to make plastic yarn (plarn), and crocheted up a couple of plarn flowers.
That's a counter on the end of my hook. Highly recommended.
I was going to write all about plarn but Tara @ Organic Sister beat me to it! Great minds and all that...
Anyway, I learnt from this site. It was not easy. But like most things, after a while it's not so bad.
We have a handicrafts festival here soon, where my friend has organised a ban the plastic bag campaign. Time permitting, I hope to whip up a few bits and bobs.
...and am waiting on more yarn to complete my baby blanket.
edit: no pattern for the blanket, but it's a gift so not showing too much here yet.
