Here is a old belt strip that I practiced on 5 mm thick,I made a groove and followed it.i never sewed in my life so for a 72 year old man im pretty happy with the results. The machine is so quiet and smooth, of course im going pretty slow. Thanks to this forum im able to get the information I need to do this. For belts,holsters, and bags this is all the machine I need. The set up was nothing, only thing to adjust was tension. I will say that the manual could be a lot better, im told that most manuals leave something to be desired.
