Building our own mini horse cart/wagon

Does anyone know where we can get directions/plans to build a simple mini horse cart or wagon. I have seen the amish in our area use what looks like almost a "radio flyer style wagon" for a hitched wagon. Has anyone ever made one before.

we in the same boat, i'm looking for plans to build a pony cart and can only find pic's f one
