I'm not exactly artsy but I'm running wild imagining all the crazy designs I can stitch onto the NeoStich DIY iPhone 4 case. It's a canvas that lets you create custom designs by threading fabric in its cross-stitch pattern.
The case is made up of tiny holes that act as a grid for your designs. You can create some pretty awesome 8-bit looking pictures by just threading a needle and no two design has to be the same. Only 18 bucks and comes with a few spindles of thread. [Connect Design via Fuck Yeah Embroidery]
