For this corset and the other ones of the same collection I used a regular industrial machine, but I had many problems with skipped stitches in bulky areas, reason why I got a walking foot machine; no skipping anymore, plus I can use thicker thread for top stitching.
I've seen a walking foot machine before, I believe quilters use them. That makes a lot of sense now. I also remember it being around $10,000...ouch. Thanks for taking the time to explain that to me. I'm really impressed by your work. You just set the benchmark for where I want my own work to be. I can't wait to see what your working on next.
There are good walking foot machines for US$1,500 (new) in the US, or you can take a look at Craiglist for used ones, you might run across a great bargain. These machines are built to last (the good ones at least), so an used one is a good investment, just make sure the machine has been serviced
