This is very interesting about types of floor covering for a sewing studio. My sunroom/sewing room has hard concrete floors, but I would love to carpet the area, eventually. The rest of the house, except for bedrooms, is terrazzo flooring from the 50's, so my legs ache enough by days end. I worry about pins and bare feet (I'm always barefoot)
in carpet, but I guess the solution would be a low nap carpet like Judy suggested. For the time being, I'm stuck with the concrete though because we have a geriatric cat that sometimes misses the litter box in the corner of the room!
