I used clear nail polish and Martha Stewart glitter.
I started by gluing on clear nails. Then I clipped them the length I wanted and filed the ends. I painted the tips with clear nail polish and sprinkled the glitter on top. Once the glitter dried on I used metallic beads and nail glue to decorate the tips. I cut some watermelon slices from my clay canes and glued them to a few nails. I went over the nails with a top coat and waited until they were dry.
