Just think how much you'll enjoy being home again with your knitting needles handy. It kinda makes the end of a vacation seem a bit brighter, eh?
I sure hope you have a knitting project on the needles or at least one lined up (with yarn in hand). I'd hate for you to suffer withdrawal due to either not having a project to knit or not having yarn to accomplish said project!
Do you have a picture that sums up your vacation? Would love to see it!
