I put my white Singer Featherweight in a Coleman rolling cooler. It is not big enough to fit the case and machine. There are several pockets on the outside (including one on the lid) and has a firm plastic lining on the inside. I have plenty of room for the machine, fabric, threads, supplies, etc.
I just bought a small Tutto for the FW. I can put the machine inside the case in the Tutto and still have room for fabrics and miscellaneous stuff.
