1. Your list of components is very short. Depending on how big you want the earrings, one straw should make two. You need a large safety pin to make good-sized holrd. The only other thing you need that's not pictured is glue.
2. Using craft scissors, I cut four 1.5" pieces of straw. I glued two pieces together then worked on attaching the hardware before completing the gluing.
3. To attach the hook, slide the pin through the straw piece. Top center as pictured.
4. Open the hook, slip it through and close it again. Then glue the other three pieces to the top. That's it.
