That sounds like a real adventure in textiles! Start with the blanket’s weave—if it’s a coarse cotton or a bit of linen, it’s already got a nice texture that can act like a base for a camo pattern. Grab a small paint pen or fabric marker and sketch a broken‑green, dusty‑brown outline in the places where the jacket will get the most sun and mud. Then, using a sponge or a tiny brush, dab in darker greens, grays, and maybe a splash of rust orange for depth. Keep the shapes irregular; nature loves randomness. If you’ve got any old patchwork scraps, cut them into little squares or rectangles and sew them into the pockets—those little “pockets” become part of the pattern too. It gives the jacket a bit of camouflage flair while adding pockets that actually hold things. For the pockets, use the same canvas for a bit of reinforcement. Pin a double layer in the pocket area and stitch it by hand or with a sewing machine—stitching all over the seams will both add texture and strengthen the fabric. When you’re done, hang the jacket out in the sun for a day to set the colors. That way, when you’re out there, the jacket will look like it’s already part of the environment. Happy stitching—don’t forget to let a few stray threads show off your creative flair!
