I was looking for a cool crown for this years costume, and all I could find was paper, or felt crowns...King Henry VIII would never wear a felt crown....enjoy my 25 dollar crown.
I bought a 8-6 inch reducer from the HVAC section of Lowes...
Measured out a pattern and using tin snip cut the pattern. Used my Dremel to remove the sharps and sanded to ensure all edges were knocked down.
Applied 2 coats of Rust-oleum hammered finish antique pewter
Cut batting and installed. Like an hours work not including 24 hour dry time for paint. Enjoy.
