I used 4 pieces of light blue 3/8" wide grosgrain ribbon, one for the body, one for the little piece that scrunches the body to form the tail, and two for the fins. Sorry, no measurements, I tend to just eyeball it. The colors are kind of altered in the photo, but the background ribbon that the actual alligator clip is covered with is a pale aqua with white polka dots, reminiscent of the sea but with an added fun factor. Because I found polka-dot ribbon at the store and I simply adore polka dots. So Fishy swims in the Polka-Dot Sea, basically. The eye is just a tiny little googly eye sold for crafts, made more fishy by using a dot of blue puffy paint to stick it on instead of glue.
For this clip, I tried out the idea for no-slip grip I saw here (she is just so incredibly creative and talented).[..and liked it so much, I went back and added it to the other clips I'd made previously.
I plan on using this on all of my clips I make from now on. One roll should last pretty much forever.
So this is my first attempt at ribbon sculpture. I'm now hooked and I have loads more ideas floating around my brain waiting to be translated into ribbon. The hardest part is decided which one to do first!
