Couples leather passport covers. Made with K40 running LaserWeb, & a generous dosage of patience.
Thanks to @Ariel_Yahni_UniKpty for sharing his template for size reference (also borrowed the extra pocket idea). Very happy with the end result.
Cowhide leather, 2 coats of red dye, 1 coat of Seal & Shine, 2 coats of Edgecoat. Tested colour fastness (by wetting with leather conditioner). Nothing rubs off onto cloth, so seems all is good.
