My child think's they're too old to have their name on their water bottle, but would like a way of easily identifying their bottle from their peers look alike bottles. (We still have some classic stickies with their name on them.)Answer:
Simply cut the icon off the classic stickies you own. (Be sure to round the corners for longer lasting wear.) Decorate bottle as desired.
Also works with skinny-minis™.
If you have children with sibling-germ-a-phobia (as in, "Ewww, I don't want to drink from the bottle top if he's used it before, even though it's been thoroughly washed") consider taking a thin slice of the same colour label and using it to match bottles to bottle lids.
