I know removing labels is a pain but I think a label just adds to the appearence. I use a home computer I print 9 labels to a A4 sheet. I am thinking of using thicker paper as it tends to disolve before it peels off.
I do not go into flashy designs just make type and bottle date (Try and demonstrate)
I print the labels when its conveniant and just stamp the date when I do the bottling.
I find an ordinary paper glue with spots applied to the corners holds it on and in water they fall off.
I am experimenting with a fountain pump as a bottle washer
