i used adobe illustrator, and im pretty happy with the results. happy enough to leave it be, but perhaps thats laziness more than anything. im planning to print them at work...nothing too thick...and using milk as the adhesive. the shape shouldnt be too hard to cut out i dont think, but a nice square shape would have been easier.
im excited, because i just transferred the batch to the secondary yesterday...and it smells delicious. it has a cool cherryish tint to it too, kinda like the color on the label.
