I forgot to get a close up but here it is in use.
It is a wool Michelob light beer cossie. MIL only drinks that beer and regular sized cossies are to fat and short to fit this thin and tall can. The next time we go over I will have to take closer shots of it.
It has a flat bottom with a stabilizing rim all the way around so she can't tip over. And you can kid of see the finger ribbing I did for better gripping of the can. The pic is not showing the colors well, it is cranberry, purple an shades of orange, it came out nice and stripy. It took me 3 hours, a pattern out of my head just by having the measurements of the can, and it is crouched mostly single stitches.
