Make sure it will fit your machine. What about future machines? Will they fit?
Is there enough space to for the quilt on the table when quilting?
Personally, there isn't enough storage space in the units to function the way I need them. I don't want a bunch a little cubbies and have to remember what is in each one.
Do you have electric in the middle of the room for the machine or will you need to run cords? Perhaps the unit will git against the wall. If you store items in the cubbies, are they going to fall out when the doors are opened. Just my concerns and two cents for you.
