Waxing Tips

Hi everyone! I just started to wax my legs and underarms with a roll on waxer and had some issues. I cannot for the life of me get all of a sections hair in one pull. I have wax residue all over me and can never seem to get it off. I applied baby power before each pull and have tried to go in the right direction. Are they any tricks that can help me get a more efficient wax at home? I’ve been watching a lot of videos but I can’t seem to figure out what I’m doing wrong!

Thanks!
