About to throw my crochet hook out of the window...

[PotatoPolly]

Please can someone help me?!

I'm trying to teach myself to crochet, I'd like to make a blanket of granny squares I think (although any other suggestions are welcome!)

I've managed to teach myself the chain stitch and slip stitch, and can do a treble stitch onto a long chain, but the pattern is:

Step Two: Round One
Ch 3 (counts as first tr), 2tr in ring, ch 3, (3tr in ring, ch 3) three times, join rnd with a sl st to top of first ch. Fasten off yarn. Attach next yarn to any 3-ch corner sp of rnd 1.

And I just can't get my head around it!

Pleaaaaase someone save me!

Thanks

I couldn't get on with youtube videos as they went too fast when I was learning to crochet. I love Attic24's blog as she has step by step photos so you can really see what she's doing.

This is a very clear tutorial.
