If you've ever wanted to crochet a granny square, and I hope and pray that you do, you'll want to know how to crochet a beginning ring.
I dearly love granny squares.
It weirds me out a little, but I'm pretty sure my granny square numbers are somewhere in the low thousands by now. And every last one was started with a beginning ring.
Such a simple thing, but it can be a little tricky to get the hang of when you're first learning about the wonderful and glorious world of those magnificent crocheted squares.
Luckily there's a video for that.
And once you get started with that one little ring, you can crochet any number of things. Amigurumi, hats, bags, my preferred squares, or anything else crocheted in the round. The world is your yarny oyster. I don't even care that that sounds nonsensical, and somehow gross. Learning the first few techniques of anything new thing--beginning rings in crochet, the first few rows of knitting, learning scales in piano--can be so foreign and strange that it's sometimes more difficult than any of the complicated things you learn after that. It's not completely hyperbolic to say that once you can do this, you can do anything. So do it!
No really, go try out a beginning ring right now. Go forth! Crochet all the things!
I think you'll be great at it.
