Yes, this pattern is a free download on Ravelry, which you can download without being a member and now available from Docstoc.com from the tab above (click menu to download) or here. It originally appeared at Crochet Pattern Central and has gone viral since. It was the first pattern I ever wrote, so there are a few additional things I would like to add to make it easier for those who had questions:
Hook size-M/N-9 MM (depending on the hook manufacturer, it could be an M or an N hook)
This makes a great stroller or car seat blanket, as it won't drag on the ground or the floor of the car, however you can make it larger. Just make sure your starting chain is divisible by 3 (multiples of 3) and add 2 chains for the starting chain and go from there. You can just chain one at starting chain and each row thereafter for the last stitch, but the chain 2 gives it a nice edging and it won't curl, it's up to you. If using finer yarn, go down a hook size, if using single strand, go down two hook sizes, etc, but the starting chain will be with width you chose and work from there. I've made it several different ways, using single strand and double strand. Gauge isn't important and if you're a tight crocheter, then go up a hook size if it seems too stiff.
If you have questions, please continue to feel free to contact me. I just hope this helps answer some of the questions and makes it easier for those who are downloading it from Crochet Pattern Central.
