Hi, I use the tractor-fed adhesive clear plastic from American thermoform Corp. I can get 6 cards per page; three on the left side and 3 on the right. I do the front and the back of the card to allow for more information. I get 4 lines per side and I think 13 or 14 chars per line. So far I have formatted the cards in my Braille Lite and then brailled the sheets on my Blazer. I skip a line after each back side of the card.
