Yes, I am planning to list more. In fact, I shall list a monogram one today (now I will have to do it!). I work the pet ones to order as there are hundreds of breeds/colourways and I seldom work the same one twice.
I, too, find that animal collectables sell well in the other place. Sometimes they make far more than their retail price, especially if they are one of the less standard breeds. I sold a pretty diamante brooch in the shape of a Bassett for over £10. It can't have been worth more than about £5 but if you want such an item you cannot just walk into a shop and buy one. It has to be grabbed when you find it.
Good luck with the op, btw!
