I have recently become quite enamored of yin yoga and because of this have started doing a bit of hatha. Thus far, all of my practice has been done at home on carpet, but because several local studios offer yin and one even has a fat people hatha class, I'll be starting classes soonish.
For those of you who have yoga experience, what is your opinion of thicker mats (1/4") or wider ones (27" or 36" instead of 24")? I am 5'4" and about 260. Since I will be doing a lot of yin, I like the idea of a thicker mat, but will that compromise stability in a traditional class with less floor work? Is the wider mat necessary for fat people or would I be just as comfortable with a 24" wide mat? I'm particularly curious about this since standard mats are cheaper and have MANY more options for materials, designs, and colors.
