Remembered that the glue gun was handy, so while I was watching a movie, I warmed it up and glued on a bunch of the shells to the barrettes I had bought. They turned out fairly well, if a bit heavy. It'll be nice having a wig that I can work on instead of worrying about fixing up my own hair. I only made about nine of the clips--I also have a crown I'm intending to use, so I didn't want too many.
Made a large one that I can put on the back or middle of the head.
The other ones are just small and random patterns that I'm hoping will stand out against whatever style of wig I decide to go with.
