Step 1: Making the frame!
To do this, get one of the frames and put it on a table, with the smooth side facing up (the side without the grooves where you attach the back of the picture frame). Get your mesh/netting and put it on top of the picture frame. Cut up a piece that roughly matches the size of the picture frame.
Align the mesh so that it covers the whole picture frame, then nail it down. Make sure the net is *straight*, if it's wrinkly it won't work properly. I used a stapler because it's easier. If you use a normal stapler, slowly staple the mesh down to avoid bending the staples.
After the net is in place, hammer down the nails/staples to make sure they are "in" the wood, you don't want any spiky nails or staples sticking out.
Cut out any extra mesh you have (whatever is not on top of the frame) and duct tape the sides of the frames. Do not go over the "middle" of the frame, only tape the sides.
Your mold is now ready. The other frame remains unnetted, and is called the "deckle".
Now cut out the blanket in pieces that cover one of the frames entirely. After you've done that, it's time to shred paper.
