I know I've talked about this before, but I'm going to talk about it again.
This is how you crochet a double crochet stitch:
Maybe I should just talk about the double crochet (dc) stitch every couple of months. It's incredibly common and it's usually the first real bit of crocheting a new crocheter learns. It's so ubiquitous I kind of forget about. I made my sister a cowl once, that was just a wide swatch of what I thought of as granny square stitches worked flat.
She said someone at her church admired it and asked to see it in order to see if she could copy it for herself. When my sister said the woman declared, "Oh, I think I could do that. That's just a nice, simple bit of double crochet," I froze and desperately tried to remember what that meant.
Stitch names get me sometimes.
But the double crochet stitch truly is everywhere!
is double crochet in shell form (from the book Crochet Cowls).
is double crochet in its standard worked-back-and-forth sort of way. (It's the Fast Favorite pattern from Dishcloths.)
Even granny squares:
are double crochet stitches bunched together for shells with some chain stitching thrown in for good measure.
If you want to lazily fall back on sweeping generalizations (and boy, do I!), you can claim that pretty much everything is made up of double crochet stitches.
A sweater my grandmother made me that hangs in my daughter's closet? Yes.
Little baby hats? Yes.
Bags and purses? Absolutely.
Rugs? Doilies? Scarves? Cowls? Slippers? Oh my goodness gracious, of course!
The Statue of Liberty? Well, no.
BUT! If someone were to crochet a replica of Lady Liberty, you can bet your amber waves of grain and sweet aqua-colored yarn that the pattern would totally call for yards and yards of double crochet stitches.
If you're just learning this stitch, bless you. You're off to a great start. And if you're so moved to then attempt to crochet your very own Statue of Liberty, then I really bless you and hope you'll send me a picture because Google has let me down on that one.
