Thank you for the suggestions. Each one loves what they have and you all have different floors !! Want to keep it somewhat warmer, so probably sounds like a low pile carpet is a good choice. So carpet that silver pins and needles will show up on, will blend with the living room carpet that it will be in the doorway and not show dirt !!! A tall order...

I would like to have laminate for a sewing room floor.

Check out the cork - it keeps the warmth. So do some of the thicker grade hardwoods (although neither as much as carpet).

If you want really warm ... look at some of the industrial office grade carpeting. Very low loft.

or .. a very large persian type that will cover all but the edges of the room where you dont walk anyway. Also a very low loft.

I've got a low loft berber. If I had a choice to redo it, I would choose either hard wood or cork. But warmth isn't an issue for me. If it's cold I wear socks.

Anything hard surface, so that it is easy to sweep up the threads etc. Definitely not a rug.
