The most popular is definitely the basic brown, but there's always a call for something different. Like my new loopy creation (bottom left). I think I might go for some more wacky colours - purple a la Billy Connoly? Let me know your suggestions.
Ooh, and I probably ought to let you know where to look at these creatures. My website is: www.wifeofbrian.com
Thanks for looking. Do get in touch x
