My Husband made one for me. He used two half inch pieces of plywood that measured 18 by 18 inches. He drilled a hole in all four corners of each piece. Then he inserted a long screw in each hole of the two pieces followed by a washer and wing nut. I use paper towels between each layer
of pressed flowers...my board press holds quite a few layers. I then store them layered in shoe boxes. Hope this helps.

I made a bunch of them for my junior high art students. You cut two boards, 1/4" to 1/2" thick, to size, perhaps 6x8 or similar. You cut cardboard to fit inside these and then paper to fit inside the cardboard. Hold it all together with velcro. You sew 3+ inches of the "hook" side of velcro to about 10 inches of the fuzzy side so it will hook together when you strap it around the wood. Make two such strips for your flower press. This is easier than clamps or even than drilling boards. Press your flowers between the papers backed by the cardboard. Good luck.

Thanks, we're working on one now.

One more question........does it make a difference what kind of paper you use? Acid free? paper towel? or what?
