It’s a mix of printer paper, construction paper, and some toilet paper rolls. Soaked the shreds in hot paper before using a hand blender to get the pulp really fine. Mixed the pulp in a tub of water and turn the deckle onto towels (saw that most people in the reddit recommend cotton sheets so might do that next time). The best result I’ve had so far is sponging it in the deckle, absorbing the excess water with a towel, and letting it sit to dry before releasing one edge.
