I admit now that this instructable was pretty trashy, so i'm gonna make a good english longbow instructable in a couple days.
Step 1: Materials
The materials list is as follows:
1.A long, straight stick about your height. Not bigger than about an inch and a half in diameter and preferably with as few knots as possible. Best woods would be hickory, elm, osage, yew, or certain types of ash.
2.String/cord. Preferably nylon cord or other strong, manmade materials that won't stretch out or get destroyed in wet conditions, but twine works too. I used kite string for it's strength and availability.
The only tool you absolutely need is a knife, but a hand plane is much better and safer.
Step 2: Preparing the Stick
Alright, now that we have everything we're going to need it's time to get started. The first thing we need to do is to find the center of your stick. I have always just guessed and done fine but for beginners you will want to measure the stick with measuring tape and mark the center somehow.(I use a little pocket knife slash) Now go out a good 2-3 inches on either side of the center and make a little line that goes all the way around your stick. From here we start shaving off the bark. Try not to take off much wood, if any, during the shaving. I forgot a picture of this stage so here's what it should look like when your done.
