I agree with Larry,
But I think with most things except the very basics ( nails,hooks, simple scrolls etc;) it will take more than ten or twelve attempts. At this point you may understand the principles, but you probably won't be very proficient at it. You'll truly have to make 50 or 100 of an item before you can do it effectively.You may also find that if you don't make an item for a while that when you attempt it again you might have to make two or three just to "warm up" to the standard you've set for yourself.
If you have no one to work with or learn from remember to be self-critical and also analyze your work as you go along.Try to discover why what you attempted didn't work. Or if it did seem to work, don't be so pleased with yourself that you'll be satisfied with a low quality item or one that has taken an inordinate amount of time for the result.
When you use the procedures of another smith to make an item remember that this may only be a starting point for you.Once you'er able to produce this item well using an-others steps, don't be afraid to try it your own way. You may find that by changing the sequence of steps it becomes easier or quicker for you or perhaps you'll even discover an entirely new and better way.
This method might or might not work for you but it is the method I've used to teach myself for the past 40 yrs as a professional smith and still use everyday. This is a skill that no one can live long enough to learn everything about. In fact I believe a life time allows us only to scratch the surface.One other thing. by being aware you'll find that you probably will learn as much about yourself from blacksmithing as you will about smithing.
