I also prefer the sleeve. I had to make good use of the front and back of my soaps using two different types of labels. For example, I use a clear address label for the front of the soap. The front label contains my company name, logo, and the soap scent. On the back I use a white label. The back label lists all the ingredients, weight, and contact information. Play around with the type of label design you would like and print it on a plain piece of paper. Then you can measure it to the size of your band. That way you can get the font size and dimensions correct before actually printing labels. If you can dream it, you can achieve it.
