It's a 'cover' made to fit over a cup/mug. I found a tin cup at the thrift store which I think is perfect for these organizers. And... they hold a ton of stuff (as you can see!) I believe that Nancy's Notions has a free pattern for a "mug pinafore" that is similar to this. I think a tin can could also be used for this but you'd have to come up with a handle - Maybe a handle attached to the cover that has some 'boning' in it to give the handle substance..... ummm, Now I'm going to have to hit the pantry and see if I have some larger cans..... Oh, dear, like I don't have enough to do, but when I get something in my head, I have to try it!
'til next time,
