I have some that I have made. Tons of ideas out there and next to nil in cost to do it. I tend to make them on bristolboard rather than a file folder since laminated the folder doens't stay as flat as would be nice. I just tape a zip bag to the board for the pieces. I am more likely to do the game as figures on the feltboard or the pocket chart so that there is more activity for the child to do and they can vary the game meaning the pieces are in a different order each time so it seems like a new game. You can use a small feltboard and still have it set out the same as a file folder and it is more toddler friendly.
