Finally finished the personalized water bottle labels for the party! They were incredibly easy! I used the same full sheet labels I bought from the invitation address labels (from Amazon.com, only $26.00/100 sheets!). I got 6 water bottle labels per sheet– purchased water bottles from a warehouse club at $3.64 for 32 bottles. The labels were printed on a laser printer to make sure they do not bleed if the labels get wet.
The dimensions of the labels are 8.25″ x 1.5″ with 0.25″ margins. I cut the labels and then had DH put them on. I made two designs and will alternate them when I put them out. Such an easy (and cheap at 16¢/bottle) decoration! The tutorial for the Pencil Vase in the pictures can be found here.
