i'll make an attempt to put into words how to make the leather boot. by the way , i 'll wear out the wing and simply unlace some of the laces and put in a new one . takes only a few minutes. HERE WE GO
you should make a paper pattern first.
draw a 4 3/4 inch triangle.
on any one side of triangle measure to the middle( approx. 2 3/8 inch)
this is the top,,,,now measure from the bottom point to 5 1/2 inches , passing through the 2 3/8'' mark.
now from one outside point of triangle , at the top, make a radius line to the other top point, passing through the 5 1/2 inch mark.this is your pattern and you'll use it to mark 2 pieces of leather.
now punch lace holes in your leather at 1/2'' to 5/8'' from bottom point to the top points.
punch 3 holes equally spaced around the radius and one at the 2 3/8'' mark.
simply lace up each side with one side having enough extra lace to weave in and out through both front and back pieces of leather going between the quills of the feathers.
my ending knot is on the back side and at the 2 3/8'' mark.
at the lower point i also left extra lace about 8'' long ,,,it just adds to the overall appearance.
got questions? just ask sorry , i 'm not equipped to post pics
once you make the paper pattern you'll see how the thing holds the wing.
good luck later
