Step 1: Explore Your City!
I found the focal point for my ring one day in the city. It originally was used on the ground to prevent people slipping on slippery surface when it rained. However, upon discovering it loose, I picked it up, scrubbed it up and voila! Bling!
Step 2: Make It!
With some E6000 (or any other strong holding craft glue) glue your metal stud to your ring blank (available from any good craft store! I use adjustable ring blanks) and let it dry. Done! Amazing jewellery at a super economical price!
