I've been very inspired by all the cool felt play mats I've seen around the web, especially at This Little Project. When I found a little bag of Playmobil toys at the thrift store recently, I thought I'd make one to go along with it.
First I sewed the pond and the garden plot onto a standard size felt rectangle. After that I sewed that rectangle to another plain green one, which added more heft to the felt, and also a finished back side. I then made a little bag that you can fold the mat into and store the toys in.
