What a fun idea! Making play mats from wool. While this website is not an actual tutorial it does explain the process used for creating this cute scene.
I spent some time on Pinterest and found an abundance of examples for felted play mats.
How about a seascape with lots of fun underwater creatures!
This is not a play mat but I had some fun making 3-dimensional Scenes. Snowman Scene for the holidays.
Well, I better get going as I am now fully inspired! What will you create? Let me know. I’d love to hear from you!!
