And here's the tutorial that has had you all chomping at the bit, lol!
Bias binding has always intimidated me, so I only use it when working with curves. There are some fantastic tutorials out there, like this one and this one. But if those don't fit your needs, here's this lazy girl's mind-blowingly fancy technique!
