Hi. Which braid from Grants book did you decide to start with? Usually when you're braiding for the first time, something simple to understand is best to start with. For example, I started braiding a simple 4 strand round braid. I kept on that braid till I learned to braid that braid without any gaps and how to even my hands when braiding. ie: even handed meaning - a balanced braid. not too tight and not too loose and straight braiding with no gaps.
If you picked out a braid that requires you to concentrate a bit harder, you'll find yourself frustrated. By starting out with something simple, you'll find yourself learning how the braid works. For example; the structure of the braid and why it has to be done like it has to be done. Braiding is like teaching yourself how to read again, or riding a bike. Something like that anyway. LOL... I find that most just learning are not impatient with the braid. But with themselves and the learning curve behind braiding. Just as I don't know how to leather carve, there are many mufti-faceted steps to carving leather than most realize. It is finding a common ground(experience) between what you are familiar with and braiding that will aide you the best. Learning the braid at this point is best rather than depending on your patience.
Hope some of this helps you out. Don't hesitate to ask and post your images of your braiding when you need help. We are glad to help in any way we can over the net.
Best regards,
Brian...
