I was confused for a long time wondering when I was going to find blueprints so I could build stuff.... before I learned I could disassemble items to learn how to make new ones.
Instead of a generic "You need a blueprints in order to build stuff" message. Maybe change it to....
"You need a blueprint to create an item. Find a blueprint or create one by disassmbling an object" or something to that effect.
