I have a Paper recycling kit, that I bought a few years ago on clearance. But any old blender or mixer will suffice. I may want to purchase a cheap one at the garage sale or a thrift store as it's not a good idea to use a blender you use to make your smoothies. If you are using a paper making kit - use the tools and follow the directions that came with it. But you can also make your own frame by attaching fine mesh (like window screens) to a wooden frame.
Theoretically, torn paper is better as it absorbs water faster, but shredded paper worked very well for us. As for the seeds, any small flat seeds will work fine.
Make pulp. Next put your paper bits into a bowl of hot water and leave to soak for several hours or overnight. Use a blender to puree the wet paper.
Add seeds. While the frame is still in the water, sprinkle the seeds on top of it, tap them in gently. You could have added the seeds to the pulp before pouring the mixture into the tub. We used very small seeds -Black-eyed Susan- and it was easier to sprinkle them over the paper. Also, no seeds get wasted this way.
We found that drying it on the paper towel gives you a flatter paper vs hanging it to dry.
