If you are using a washer, put the washer on the bottom die first. IF the washer has a slight bevel to it, put bevel side facing up (similar to saucer for a cup of coffee)
Hold your material firmly between your thumbs and pull the material over the sharp point of the bottom die pilot. The bottom die point should now be sticking thru your material as seen in middle picture at right.
Place your eyelet or grommet barrel side DOWN on bottom die
