Well, I know that all the cosplay costumes are really, really, expensive so with a little practice I came up with an evolutionary idea to make this little project!
Step 1: Materials
2) white and blue paint or just light blue
4) paint brushes
5) circular wood pieces
6) mod podge or clear nail polish coat
7) blue ribbon
Step 2: Paint It
Paint the wood piece with the white and blues paint. Then use a blue sharpie to draw the lines and swirls on the wood piece. But they are not supposed to be that close to the top. (see thats what happens when you do it too fast.) It can be sharpie paint marker or a regular one. I just made like a quick draft because I didn't have time to let it dry.
After it dries put the mod podge or clear coat so it will be sealed.
Step 3: Glue It
After I let it dry I glued the wood price to the blue ribbon. I let that dry too before I put the Velcro on.
Step 4: Done!
Once everything's dried you can style you're necklace!
