Sew your own unique activity mat for your dog. Sew a base first and then get creative!

Disclaimer: I am not a native English speaker and not a sewer by profession, so my terminology may not always be correct, I'm truly sorry for that.
 
For some puzzles you have to get a little creative yourself as well and some sewing experience is necessary to be able to make the puzzles.
