If you provide the size of the water bottle and some kind of description as to what designs you would like I will give it a try over the next couple of days?
For example, how many designs, who for, any wording you would like, whether they are for males or females, particular characters you would like?
E.g if you had a daughter Sarah who loves Tink I could do a design with Tink saying 'Sarah's Disney Drink 2013' or something to that effect.
