So I am going to go over the basic process, but without some sort of "kit" or handmade screen setup it will do you no good...tho we are working on making some kits up and once we get that all figured out I will fill in the details!
First you rip up a sheet of paper about the size of the wood and screen you have, add that to 1 c. of water in the blender and blend until it is a pulpy pretty paper type mixture
Then you pour the "pulp" into your screen and wood setup, while it is in a tub of water...spreading it and mixing it until it covers the whole screen in a semi uniform thickness
Then you pull the screen out of the water, place it on a cookie sheet and undo the screen straps...if you are going to place anything like flowers or leaves in there, now is the time.
Then you cover your new "paper" with a piece of plastic, using a sponge (or in our case a sham WOW) try to absorb as much of the water out of the paper as you can...you will ring the sponge out many times.
Then you will remove the plastic VERY CAREFULLY from the paper, and put down some card stock. Using a solid piece of wood or something hard with a little weight you will push more and more water out, drying it as much as possible.
When you think you got enough water out of the paper, you will set it aside with dry-ish cardstock undernearth until you are all done with the paper. When you have made all the paper you want to make, pile it up, and put some heavy books on top of it to keep it flat while it dries. You can use an iron but I havnt done that before because I heard it tends to make the paper crack and weaken.
