George, those annoying little PE tags can be either snipped off if you have the right type of shears or as I usually do, place the part on a sheet of glass, I've a bit from an old photo frame, take a sharp knife and while holding the PE part either with your finger/nail tip or tooth pick, cut the tag off with the knife blade. The PE is not hard and will cut easily as long as the blade is sharp.
Nice work your doing as well.
