Here it is felted (along with one of the other bags.) After felting it's just about the right size for a cell phone and maybe a credit card. The large loop slips through the small one, effectively keeping a phone from falling out. I've never seen a need to line these, though of course you could.
I finished my wristlet a few days ago, but have just gotten around to photos, editing, etc. Here it is before felting with some wristlets in the background that I made last fall. They're in various stages of completion. Only the one on the far right has been felted so far. These are just some little bags I whipped up that I figured would be great for last minute gifts. In fact I had more but some were given away for Christmas last year.
And here it is with the purse that inspired this particular wristlet.I'll probably make some more of these this fall too, just in case.
