For me 2018 will be the year of creativity, at least in theory. In between small leather jobs for the forum, I'll be finishing up several euro-rucksack upgrades that I'll be posting soon. These are speculation projects. I've modded and taken apart lots of packs from Alice's to euro-rucksacks, and I'm wanting to create a pack now. Questions : 1 - nylon vs. canvas I have nylon packcloth, cordura, micro ripstop, oilcloth, linen canvas and cotton canvas. What is the general preference ? 2 - external frame or not ? even a light set of stays in a small pack helps with support. 3 - color : camo or plain green or earth tone. Not really wanting loud colors. 4 - size : day use only, weekend overnight or multiple day outing ? 5 - it will be top loading. I don't work with zippers or velcro. Thanks for your input.
