Wine Bottle Dribble Catchers

I saw this idea while thumbing through a knitting pattern book at one of the craft stores where I spend too much of my time. I honestly cannot remember what the book was called or even what the cover looked like but I'll try to find it again so I can give credit where credit is due. Anyway, I took note of the approximate measurements and decided I could probably improvise the pattern and even change it up a little (after all, it's basically a three inch tube with a ruffle created by two rows of increases). Below is the result. The green and brown striped one looks like the one I saw in the book. The purple and grey one is my own variation. I'm hoping I can come up with some more original patterns for these so that I can put a few up for sale in my etsy store.
