I can do the charlier cut and hold the half packs with the index finger in between just fine. It's the upcoming parts that are the problem.
My most recurring problem is that when I try to interlace the packages, the leftmost one will open too much and the right pack will slide itself entirely between two cards of the left pack instead of faroing, turning the move into a weird cut instead.
Also when I happen to interlace the cards properly, sometimes the cards will completely slide into the deck, completing the shuffle without the faro part. I realized I can avoid that if I start interlacing the cards from a diagonal angle, that way the cards don't slide and I can try and bend the right pack up to prepare the faro, but when I do that then the cards slide out instead of in and I end up with two packs again...
How can I fix those problems?
