I made 5 Tropical Bath Fish total.
Yarn: Peaches & Creme in Fiesta. The odd one out is in Gumdrop.
Needles: Size 3 (3.25 mm) double pointed needles.
The body is worked in the round starting at the mouth of the fish. When you get over halfway done, you put the ping pong ball inside the fish and close it up and knit the tail flat. Fins are added at the end.
They float in the bath, but because of the dorsal fin, they kind of tip over. McKay doesn't like that and thinks I should add some sort of weight, but Margaret doesn't seem to care when she plays with them.
I'm making up a pattern for them that will be available on Ravelry either tonight or tomorrow. The pattern will be under the Creative Commons Attribution Non-Commercial License.
