I'm constantly impressed by the talented artists who show off their skills online, and their videos are doubly impressive when the skill they're showing off takes years to master and the crafter is working at a blazing fast pace.
Here's a perfect example- a video filmed by Wired/Condé-Nast showing speed crocheter Jayna Grassel crafting a yarn flower in under 90 seconds.
Jayna creates a ludicrously speedy 71 stitches per minute in the video, and says she can actually work faster when she's not uncomfortably positioned for the sake of the camera:
I went up, saw the studio, met a bunch of people and they told me to stand behind a table and crochet while they shot aerially. Um, I don’t crochet standing up. That’s crazy. So they got me a chair and I repositioned myself. But to be honest, it still wasn’t great. As any crocheter will attest, when you crochet your elbows rest almost at your hips, hands at about mid-stomach level. Normal. To get a shot, they had me stretch out my hands so they were centered over a table... It was strange and I’ll admit didn’t set me up to do my best. I was dropping stitches and wasn’t as fast as I’d been practicing.
