Cleve I am the same way!
I might even be a little dyslexic so reading something doesn't always get through nearly as effectively.
If I can't get the "word picture" then the chances are that I'm going to be lost and frustrated.
But I have some encouraging information for you. You can do it! Here's how.....
Start by telling yourself that it's just a stick and don't elevate it beyond anything else in your mind other than a stick. The next thing to tell yourself is "I'm going to try"!!
I love a good campfire and if I fail enough times I'll have a nice one to burn some hotdogs over..lol
Get yourself a cheap full length mirror that you can fasten to or lean against the wall at floor level. I found it was a bunch easier to see my early floor tillering if I stood in front of one and watched my bow working in the mirror rather than trying to see the whole bow by looking down on it.
Next, figure out a good wall you can fasten a tillering tree(it really works better if the wall has straight lines that run horizontally). Attach a pulley near the bottom so you can put a rope through it. Now you can stand a ways back from your "stick" when you pull on the rope.Watching the limbs of your "stick" work is real easy to see at a this distance.
If you already shoot a bow then you know what one is supposed to look and feel like. Don't let the thoughts of failure stop you from starting until you can find a mentor.
I'm telling you all of this from my personal experience. It's my opinion that about the only true way you can fail is...... to fail to try.
I believe you can do it even if the 1st attempt or two isn't what you want to end up with, at least by then you'll know what doesn't work.
My nickels worth!
God bless,Mudd
