The thing that inspired this was a picture of these shower cap jellyfish that I saw on Pinterest. We decided we wanted to make a whole underwater display. I also have hung some of the jellyfish from a light in front of this display.
I made the coral from Great Stuff. Here are the directions I followed.
The border at the bottom of the display was fortuitous. Years ago when I moved into a beat up house, I found this wallpaper border for my 7 year old’s room. By the time I got around to decorating her room, she was too old for the underwater theme we had planned. I just found it a few weeks ago in my craft room. I bought it at Lowe’s in 2007. I made the jellyfish with some dollar store shower caps and white curling ribbon. I just used scotch tape to attach the ribbon to inside of the elastic. I used 9 or 10 ribbons for each one. On the display I used left over book covering material (the stiff kind for paperback books) to attach the jellyfish. I used two pieces, taking off the backing and putting the sticky pieces toward each other. I inserted a piece of fish line while I did that and hung the jellyfish from the fish line. Right now it is attached with scotch tape, but it does not stick well. If I had a needle big enough at school I may have pierced a hole in the top, threaded the line through the hole and tied a knot.
