It was easy to make! I just put in a 20x30 image and boom. I didn't need cardboard as it added too much bulk. If it's a poster, I think it's easy to stick it on the board with glue first. Walmart sells good black and white ones. Styrofoam etc. I didn't use any fasteners as it was just as easy to hang on the frame as it wasn't a heavy painting at all. If it's hard, I suggest following the instructions, well written with diagrams, to attach the hanging hardware to the back. Otherwise it was easy, looks nice and great for the price!
