Thank you Patrick.
Modifying and making equipment is a hobby that I enjoy. For every project that turns out there are many more that don't.
That makes 2 of us, I too learned from my mom as a cub scout and was expected to repair/ make all my own gear and badges. I'm still doing it and have repaired well over 100 tents (former scout leader/ trainer) dozens of packs, and assorted storage bags, although not as fancy as your stuff because my #1 concern is function and I really don't care about it's looks. All my sewing is done on a regular 40 yr old Kenmore that used to be owned by my mother in law, While much of the time I'm making/ repairing stuff sacks for various items, my main passion is tents, especially hot tents with all the accessories (welding / fabrication is another hobby), I've made and given away 6 so far ( all to friends and local scout leaders) each tent was made to improve on the design of the previous one. #7 will probably be a keeper, as will stove #11.
I've literally tweaked every tent I've ever had to make it work specifically for me, whether it's to add a 4" drip edge to a fly, install a more robust 2 way zipper, add tie down patches and velcro, or remove useless windows and replace them with lighter coated nylon I've done so many zippers I buy it by the yard, and most of my repairs/ alterations are easy to spot because I use a lot of cannibalized fabrics to keep them out of the landfill, so colours and types of fabric are often mismatched
Everyone that criticizes me for using it gets the same response "I'm good with machines, and it's a machine isn't it?"
