I would lose the carpet if you have the choice

No carpet at all in this house...hard wood and ceramic tile! We have cats and it's easier to clean up after them than with carpet. I have rolling desk chairs at my computer desk and at my sewing machine, and have fun rolling all over my studio on my hardwood floor! :)

I have a cork floor...it has a look of wood but has some cushion to it. I really like it!

I had hardwood put in and just love it. There is one small -- very small-- negative I found. I have rollers on my sewing chair and my computer chair and I wound up with a small rug under the sewing chair because I tended to slide backwards as I used the footpedal. Pins are a danger in our house. My dh is diabetic and has neuropathy in his feet and legs. In short, he can't feel if he steps on and gets a pin embedded in his feet. It's really easy to get the pins swept up when I'm done, but I don't do as well with a vacuum where the pins may get twisted in the carpet's fibers.

Since the carpet came with the house, presumably you don't know what's under the carpet. There may not be a wood floor under there, but plywood, and you would have to put down a floor. In any event, how do you like your
wood floor? If it's perfectly okay for you, get the wood floor. If you're unhappy with it, get carpet. I like the
feel of carpet under my feet because I have a tendency to take my shoes off. A suggestion might be a wood floor and an area rug. I have a wood floor and an area rug, and I like it a lot. I don't see that it makes a difference as far as sewing is concerned, only cleaning up. I don't find a difference between seeing items on the floor on the wood floor and the carpet. I see them both equally well. My point is whatever is comfortable for you is what you should get.

I used to have carpet and HATED it (for all the reasons stated above). I now have laminate and LOVE it!! It's not only easy to clean and find "escapee" pins, it's great for rolling my chair from my work table to my computer.
