I did not. The leather itself, though, was soft and flexible. And it stretches when you fit the strip over the wheel, too, because your edges on the inside should have smaller circumference than the center of the strip on the outside, in order to avoid having folds/wrinkles at the seam. I inspected it, before stitching, to estimate how much I should trim from the sides. I stitched it loose at first, then carefully gave it more tension to see how it fits, and it stretched just fine like a baseball skin.
I bet they do not use the same leather for shoes... This actually goes along with my original comment regarding having no idea where to get the right kind of leather to do the proper job from scratch.
