I used a regular domestic machine, though I have to admit it is not a cheapy. It is a pretty decent machine. We were able to pull the V92 through a very small section of the front bolt rope that had 8 layers. Most of our sewing was done through 4 layers and we had no problem. We did have some problems with the bobbin getting tangled at times. It was easy enough to fix and only slowed us down a little. I highly recommend the bonded polyester V92 from Sailrite.com. It was very very easy to work with. Most of our stitching was zig-zag, but we did use straight stitching at times. I'll attach a picture of the sewing machine.
