I don't know what they are because I threw away the package but I got them in the jewelery making area at WalMart. They are kinda a pearl substance with tiny holes on each end and somewhat curved, not flat. Wonder if they are Abalone. I happened to have some tiny dragonfly and fish shaped brads for scrap booking so inserted the prongs through the holes and tied a brown very thin leather strip on the backs of the brads. I then bent the prong over with needle nose pliers. I should have used rub on lettering or had my stepson letter them for me. Oh well it will come off with polish remover. It's just a Sharpie.
There is the same problem with the soap and lotion dispensers in the counter by the sink. DH thought they were silly because no one would know which was what. I found little round rubbery stick on bumper scrap booking doodads with letters in them. So put an L on one and an S on the other.
To be honest, that shower/tub won't be used by us I bet. We have two other bathrooms and both have showers so we're more apt to keep this one more for show than actual use. I won't even put up a shower curtain. The kids are grown and out so we have a lot more room than we really need. I have lived here 36 years.
Pete is a little allergic to cameras but just didn't happen to be facing it when I took the pictures. He NEVER takes pictures, wouldn't have any idea how. I have a picture taken on a cruise almost 7 years ago that I'll post but a lot of water has gone under the bridge since then. He just turned 60 and I am almost 65. The color is a bit off, seeing I scanned it into the computer.
