Here's an idea that i do..
My room is soooo full, not sure how it happened
but theres days when its overwhelming... I was gifted a huge mat that was waaay to big for them.. I had no space either but it was FREE !!! I ended up putting it on the formal dining table and it fit !!!! SO when i need it, its there and when its not in use I cover it with a table cloth... and it becomes the dining room again..
