This week I purchased one of those heavy duty vinyl floor mats to put under the chair at my sewing machine. The kind that has teeth on the bottom that sink into carpet. Not only does the mat make it easier to move my chair, it keeps threads and crumbs from getting into the carpet, and makes it easier to vacuum all those bits, too. And an added bonus....the mat grips the foot pedal so it doesn't creep....yay!! Mat was about $20 at Sam's. This obviously wouldn't work on hardwood or tile floors, but since my sewing room began life as our guest room, it is carpeted. Hope this is helpful....have a wonderful weekend! Karen
