After a year-and-a-bit of sewing many seams together in the name of Ruby in the Dust, I've finally got myself some labels, yes! They were from Fancyweaver, and were priced pretty well. If you want your own, you should order soon as their prices are going up in October, as far as I know. They're woven and have a no-fray edge. I read about them here, and the advice about leaving a 15mm at either end of the type was good; it leaves a bit of space for sewing into seams.
