I did mine with the denom dirctly over an edgespot
I was very anal about placement, I found that when I started that I'd lightly place the label, then if it was not perfect I could use my thumb with pressure to slide the label over. The labels I bought had some incredible adhesive, I completely messed one up and it was a bear to remove.
One note, be careful with the krylon, I went a bit heavy on my first sheet and it appeared to compromise the adhesive a bit, I just did 2 coats after that, they're holding up great. I didn't peel off the backing to spray, I was afraid the krlon would seep into the adhesive and screw it up. It took several hours and I lined up the labels so they matched each other.
Unfortunately (not really) I bought a set of Martini Clubs and am now selling these, only a few 4-5 person games with them, some have never been touched.
