These buttons are handmade with the use of Sakura's Crystal lacquer. I like this product the best for attaching paper to buttons. It holds well and doesn't bubble.
For this project I used clear acrylic buttons, tiles and charms. These were attached to Graphic 45 paper by putting Crystal lacquer on the are of the paper I wanted for my button and they laying the acrylic piece on top. Allow it to dry and then cut it out with scissors.
