There was someone on another board that used the FW to make a carrying case for it. Used a blanket, canvas and fabric scraps for lining. It also had webbing for the handles.
The Featherweight did do a pretty good job getting through the thick material. There was a part where I was going through three layers of webbing as well as 4 layers of canvas to do a box stitch for the shoulder strap D rings. Here I had to turn the wheel by hand and it did skip the occasional stitch. For the sake of comparison I did the second D ring box stitch with my 201 and it sailed through it flawlessly.
