It doesn't matter if you're talking about the original Nichelle Nichols or the reboot Zoe Saldana Uhura, there is no denying that the character is a perfect candidate for a Nerdy Girlpower blanket. Personally I love Uhura (and Star Trek in general.)
But this isn't about how awesome I think Uhura is. Its about the pattern for the blanket square.
It is knit flat and double sided. I use Caron Simply Soft yarn, with size 8 US needles, but you can use whatever yarn you like, so long as you're consistent throughout the blanket. (at the end you'll crochet them together and you want them to all be the same size..) Anyhow, here is the chart for my Uhura square
Here's a link to a video showing how to knit doublesided.
