please. 
My ds is 17 mo and recently I've watched a few story telling videos on you tube where they use what seems to be a felt board plus felt animals to illustrate the story. I thought this would be a fun thing to have at home, but would love some advice from people who have used them before, as I've never seen one in the flesh.
How big should I get the board? A quick google shows many sizes. This would be used at home and occasionally at a toddler group I go to, with about 5 toddlers.
What's the best background colour?
If I want to make one myself, how do I go about it?
What about the figures? Felt? Laminated paper+ velcro?
Anything else I should think about before spending money?
TIA
