Hey, I hope someone can help me out with this, SL has changed a lot and I have no idea how to use BOM stuff. Bought a Lelutka Nova Head pack and managed to figure that out however, I have no idea how to use a head applier that I bought. I tried looking at youtube vids but no actual vid on these specific appliers. The one I bought was from Glamfair, Lelutka Nicky Mesh Head Applier and I've attached the pics that show but don't really work. Not sure what to do? Please if someone can give me some insight about how this works that would be great thank you.
