Me again, i’ve been watching a lot of leca videos but still unsure whats the deal with it, i decided to boil it to make sure its sanitized since it came with a hole in the bag , how do you prep them? and honestly whats your tried and tested way of using them & when do you use them? Or is there someone in youtube that hit the nail on the head on tutorials? Are these the right kind? Any advice is gladly appreciated! 🙏🏼
