Have any of you tried applying nail tips and the overlay yourself? Even if you go to a salon, have you learned anything watching them? I could use some pointers if you have. I usually do a full-cover nail but this seems to be better both for strength and nail health. Some woman I met does this herself & her nails are absolutely BEAUTIFUL. So with her encouragement, I invested in all the stuff. I'm about ready to attempt this feat. Any suggestions?
