I think they’ll do just fine. As for the finer points, they will work their way into the way you tie one at a time. Materials will change the end result but aren’t needed in the beginning. Get a few and just try different things, like how to hide your thread and how not to add too much on the finish. Patience most of all, don’t rush yourself to do a jig like someone who has been tying for a long time. You will get there.
