Greetings from one newbie to another.
I also started learning to faro approximately two weeks ago. I just want to echo some of the responses here. First, try more cards, not just new decks, but different decks from different manufacturers. I personally find brand new USPCC cards (like your bikes) impossibly difficult to faro until they are beat in, this aligns with what winterline mentioned about the edge shape. Second, don't force your packets together, if your cards aren't starting to alternate stop, re-align your packets, and start again. Applying more force to cards which aren't staggered wont stagger them. Finally watch more videos from various experts. I watched at least 5 different tutorial videos on how to faro, mix and match what makes sense to you in each video. There isn't one best way to learn.
I like the idea of posting a video of your attempts, sounds like this forum is full of kind people who want to help and that would be the best way to catch pit falls.
Keep at it, practice is the only way.
