How to use it?
1>Test compressing a snap before starting. Don't need to test on frabric, just get a feel for the setter tool by creating a snap from the two snap halves. This will makes you familiar with the tool but also allow you to adjust the compression of the tool via the thumb screw adjustment.

2>Use hole punch of the proper size to accommodate your snap size(seriously, don't skimp on this step)

3> Insert base of snap (male size) through hole in fabric

4> Place top of snap over base of snap ( sandwich the fabric between the two snap halves

5>Place the setter tool over the snap halves in the proper orientation (Note: Make sure the setter tool is loosened by backing out the adjustment thumb screw until you can reasonably compress the snap without having to apply too much pressure). If you can't squeeze close the setter tool then the thumb screw is in too far ... back it out.

6>Tighten the thumb screw and compress the snap a second time. When installed properly, the snap should not spin if you try to rotate it. After a few tries you should be able to loosen and tighten the setter tool properly without much effort.
