Excellent article, Deborah!
I was thinking about yoga space recently. I live in a motorhome and the only room i have for my mat is right in the middle of the floor. The space is barely wider than my mat! But it's what I have to work with and i will not let that keep me from my practice.
I do wish I had a proper wall to work with for inversions. I have to mess around to find something to lean on. Again, my solutions are imperfect but I will work with what I have!
