You're probably not too good at sewing, but don't blame yourself. It's really you lack of equipment. If you had the Brother Quattro 6000D, you'd be a regular embroidery master. This monster of a sewing machine has a 7-inch HD LCD display on board as well as embedded runway lighting. It has a camera next to the needle, letting you see up close exactly what you're doing, making sure you don't screw things up.
There's no word on pricing or a release date, but it's safe to say that this thing will cost a pretty penny. But think of all the money you'll save making your own clothes!
