The book is right in the making of it and wrong in one or two of its figures, and that is the whole of the trouble below. Every line here is a small repair; read each one before you cut a spar or mix a drop of paste, and the kite will fly. Where a repair itself came out crooked I have gone back and repaired the repair — and I am sorry for the muddle. If you find a figure you doubt, tap the line to dispute it and I shall set the matter right at the foot; or walk the blue mark with the arrow keys and press Enter.
