I did that yesterday, embedded some wire into wax foundation strips. Made the mistake of doing it on a hot afternoon, in my shop, so some stuck to the surface I was rolling on. I also ran off the wire a couple of times, and made a few holes, but I figure the bees will fix it. Don't worry about it too much, bee keeping is not an exact science. Mine did not come out perfect either, same as yours, either too much or not enough scattered here and there.
