The Assorted Materials producers will drop Big Pliers Level 1 which can be merged up to Level 9 Crafting Desk. Then, the Desk needs to be filled with Sewing Pattern Level 3 (dropped by the Sewing Machine) and Amethyst Level 4 (dropped from the Assorted Materials). Once the desk is filled, it will become Crafting Desk Ready and it is ready indeed to drop some photos!
