I think that out of all the (meager) patterns I've designed, the best and most popular one to date is my owl coffee cup cozie ... so far 393 made on ravelry and 921 in queue, to date.
For some reason, though, I've gotten mildly obsessed with checking out its queues more so than any other design I have. The highest number of queues in a day has peaked at 10, over the last 180 days (back in September) and peaked at 5 in the last month.
It's a given that this is a small project, and many have posted that it's a great, easy way to learn cables.
I would love to have another day of queues peak at 10, or even beat that record. I've no idea how to have that happen, but it would be stellar. Valentine's Day is a week away... I wonder if this would make a great gift for that occasion?
