I bought the pattern and the foam squares. I had a very hard time figuring out which side of the foam squares was the sticky side. I called the shop and she didn't know so I called the manufacturer (bosal) and they didn't know either. She said she would find out and call me. Never did. I decided to try a small corner and guessed right. Trouble was the glue didn't hold, so it didn't matter anyway. I had a devil of a time figuring out the instructions. Never again. I will never use the foam filler--too stiff for my tastes. Lesson learned--it's not as attractive as it looks in the picture. imho
