When we made blender paper in kindergarten we did not let it dry in the forms. Put the forms on a screen over a can and poured the paper/fabric pulp into the form. After it drained we turned it onto blotting paper to dry. With the glue binder you might turn the fabric mush out of the mold onto plastic wrap or glass or teflon. I should hold it's shape before it's dry and sticks to the form/mold. I suspect it won't stick to the form with the pan spray or nothing at all depending on which white glue you use.
