Felt Story Boards

When I was a kid, I had a small felt story board that was just a plain green.  I then had a box of felt fairy tale characters.  There were pieces to build a castle with, as well as a king, queen, princes, and princesses.  There was a fire-breathing dragon, and other small animals.  It wasn't complicated all - the felt pieces were just outlines - no embellishments or clothing or anything fancy.  But, I spent hours with the story board. I loved making up stories about quests - and it laid the foundation for my enjoyment of the Knights of the Roundtable stories when I got older.  A recent search of felt storyboards on amazon.com turned up some really fancy storyboards.  They seem overly complex - and while I know they still leave room for imagination, I still think simpler is better.  I'm going to keep searching around the internet to see if I can find that old felt box that I had (I feel like it was made by a Scandinavian company for some reason...).  In the meantime, I'm trying to design a general board for Ben - thinking that I could then have felt categories - such as nursery rhyme characters.  But, given Ben's age, I was thinking we could start out really simple - teaching him shapes and colors.  All we need, for example, is a red square, a blue circle, and a yellow triangle (and maybe a more complex purple star or green diamond).  But first, I have to figure out how big to make my felt board...
