Kukkii-san I chose very light materials to make an elegant version of the Summoner's Staff to match my Amano style costume.

Step 1 (upper left)
I cut the ornament from VERY heavy cardboard and set in pieces of light cardboard for the inner circle (the parts that will later be painted blue). The cardboard ornament is set into a deep groove in the wooden staff and fixed with glue. The rings around the staff are made of stripes cut from craft foam.

Step 2 (upper right)
I added modeling clay to form the tip of the staff and started pasting the ornament with papier-maché (silk paper and wallpaper paste).

Step 3 (lower left)
After adding several layers of papier-maché, the staff is ready for painting! It's important to paste the most fragile parts of the pattern very thoroughly, i.e. the lower curve of the ring and where it joins the tip of the staff. The glue stabilizes and hardens the cardboard so it will not bend too much and break eventually.

Step 4 (lower right)

With about three layers of acrylic paint and transparent varnish each, and one layer of metallic effect spraypaint inbetween, the Summoner's Staff is finally done. I would then wrap velvet ribbon around the length of the staff in a spiral until all the wood is covered by it, and finally add the bells and beads on a leather string that dangles from the lower end of the staff. You can see the finished staff in my photos of the completed "Summoner Yuna" costume!
