This is 1 of 4 pull tabs sewn onto the boot shaft. Front of a boot shaft, sewn zig-zag on front seam and showing pull tabs and tiered cut of top rim. Side view of a boot shaft, no rear zipper yet. Boot shafts with zippers sewn in. I sewed a faux seam around the bottom rim of the boot shaft, but used super glue to adhere the shafts to the shoes; taped for glue line marking. I used a negative vinyl mask to paint in the boots' chevrons.  Painted with brush and Jacquard fabric paint. As with the original boots, black lines follow the seams of the boot shafts around the front and sides. The original boots have no toe caps, but these Calvin Klein shoes do. The original boots each have a zipper along one of the black lines, I believe; with a 3-panel shaft, not 2 panels as I did.  I simply placed my zipper in the back, centered.
