I like to make my own kit if I have the means to do so myself, but in respect to the "traditional" aspect, I'm kind of in the middle. I like the look of canvas tarps, tents, rucksacks and so forth, but I cannot justify spending a fortune on something that is also heavier than a similar item made from more modern materials. Wool blankets are out of the question for me, the insulating value to weight ratio is just not as effective as modern synthetic or down sleeping bags.
As far as clothing, I like to combine the best of both worlds - wool blend socks, poly-cotton trousers, cotton-synthetic blend base layer, as well as one made from 100% merino wool, synthetic shirts for the summer (quicker drying than wool, without a doubt), fleece pullover midlayer, wool sweater midlayer, wool blend swacket (sweater jacket combo) midlayer, German army sympatex (equivalent to Goretex) flecktarn parka shell, Tilley T3 duck cotton bush hat for the warmer months, ushanka hat with rabbit fur lining (animal furs repel snow very well thanks to the natural lanolin oils, and I would argue they give a better insulating value to weight ratio than wool), goose down gloves, and synthetic insulated wool-lined gloves. I also have an Austrian army parka, which I believe is made from canvas or a poly cotton material, but I haven't used it in awhile mainly because it weighs twice as much as the German army parka.
I would say that if you are going to incorporate traditional gear into your kit, be mindful of the weight you'll be carrying, and try to get the best deal possible. Most of my clothing, for example, was bought on a closeout sale or is military surplus, so I didn't have to spend a fortune. I cringe when I see ads for Mackinaw virgin wool jacket and pants sets, directly targeted at the Bushcraft community, which can run up as high as $500 (I kid you not), especially when certain people online promote these products as the latest Bushcraft fashion hype. Be careful not to fall into that trap and spend wisely.
But as far as making my own "traditional" Bushcraft kit that isn't a great weight compromise, I'm slowly getting into leatherwork and made myself a fire kit pouch...
Nothing super special, more of an experiment than anything else, but I am pleased with how it turned out
. I also recycled a Starbucks Christmas coffee bag made from cotton and linen into a tinder collection pouch - very light, and because it's a breathable fabric, wet tinders will dry out if I stuff the pouch in between my clothing layers.
I also tinker around with stone tool making, if that counts (though perhaps it would better fit the "primitive category"), as well as open-weave vine basket making (again, probably more into the "primitive" category), and some wood carving here and there, though my carving efforts are definitely outclassed by the gifted folks on this forum
