Make sure your flooring choice is comfortable. (for your back, legs, feet)
Yes, you spend a good deal of time sitting at your machine(s) but, you will also spend a lot of time standing at your work/cutting tables.
Ceramic tiles look nice and are easy to clean but are very hard on your back, legs and feet.
Carpeting is nice but LOVES to collect loose threads and over prolonged standing, can become hard on the back as well.
Hardwood flooring is generally easier on the back, legs, feet than the above and might be a wiser choice.
There are also lots of vinyl cushion flooring choices which may be an option, and are easy to maintain.
Whatever flooring choice you make, you can also get fatique mats in various sizes to lay in areas where you do most of your standing.
Word of caution: Because this is a basement location, MAKE SURE, you have sealed the floors and walls to prevent moisture buildup - this can and will lead to mold problems down the road.
