They do look nice but consider how you function when you sew. Those tables wouldn't work for me. The drawers and the thread holder are too small to function for my needs.
My dream space would be to install some 36 wide kitchen cabinets with easy close drawers. The inside height would be about 3 to 3 1/2 inches so threads, scissors, etc are easy to see. All like items are stored in one place.
My other concern with this style of table is about changing machines. Would a new machine fit in the same cut-out? Did I just save you some money?
