Hand strength is a huge part of the lepaul spread. Initially the cards will just go everywhere, honestly, but your hand slowly builds the strength. If I try using my other hand to lepaul spread cards just fly everywhere because I havent built the strength in that hand. It's knacky, but you will get it with practice, it only took me a week or so to get down basically from scratch and then of course perfecting time. Once you get the cards to spread a little, go very slow, this move does not work if you go fast (not when you are learning anyway)
