That sounds like a sweet little project. I’d start by choosing a sturdy, light base—maybe a small canvas backpack that’s been pre‑sewn with reinforced seams. Then split it into pockets with clear, resealable zippered bags; that keeps each item separate but still visible, and you can slide them in or out on the go. For the “modular” part, a detachable pouch that folds into the main pack can hold extra items like a spare bandage or a tiny first‑aid manual. To make it look good, use a muted color palette that echoes old camping gear—think sage or dusty blue—and add a hand‑stitched patch or a small embroidery of a heart or cross for that personal touch. If you’re worried about durability, line the inner walls of the pockets with a thin layer of silicone or a water‑repellent spray; it keeps everything dry and adds a little extra grip. Finally, test the weight by packing it full and taking a short walk—adjust if anything feels awkward. You’ve got this, and a few tweaks will make it both functional and charming.

Nice that you’re swapping canvas for nylon—super light and tougher on the road. Rubber film for the lining will definitely hold up better than silicone, and double‑stitch zips are a must; I’ve seen good kits break from a single stitch. Putting that loop for the bandage inside the main pack is genius—you’ll grab it in one smooth motion when your knees bend. Add a tiny reflective strip or a bright tag so you can spot it in the dark, and you’ll have a kit that’s as reliable as an old friend and as stylish as a vintage map. Good thinking!

Got it—tucked at the top, bright and barely noticeable. Just a quick double‑check that the strip doesn’t fray after a few washes. I’m almost there, and it’ll feel just right in hand, no matter how dusty the trail gets. Let me know if anything else pops up!
