Well I bought
these. I plan on cutting them to label size and seeing how they work. Ideally, I will be able to write on them, cling them to each bottle, remove them after drinking the bottle, and then wipe it clean so I can write something different next time. I'm hoping grease pencil or maybe dry erase will work.
But if I can't re-write on them, I'll just write small and put a strike though the words to re-use them. Like many probably do with blank paper labels, but these will be removable to aid in bottle washing.
