Never noticed this thread. I've made a handful of bags for various bikes and trips. I mostly use Cordura, ripstop nylon and x-pac, but I tend to use whatever I have on hand. Fortunately I have a local upholstery shop that stocks a good selection of technical fabrics and general bag hardware.

This was one of the first I made, a 6"x11" barrel style handlebar bag. 1000D Cordura exterior, VX21 X-Pac liner. Interior and side pockets. Not a great picture of the bag, but the only one I had on hand.



I needed bag for my basket, but I couldn't find anything for sale that had all of the features I wanted, so I made this one. Again, Cordura exterior, with a 2.2oz ripstop interior. Rolltop closure, rear zip pocket. I've used this for commuting and a couple short tours



Here it is, overstuffed, along with a half frame bag I made for a short dirt tour of the mountains around Prescott, AZ. The frame bag held nothing but tent poles and a 3L camelbak bladder, which was essential for this trip. I also made the little roll top saddle bag you see tucked under the seat.




I've made a couple of these stem bags. I initially made them as bottle holders for my Brompton, but I mostly use them as drink or phone holders on the back of a basket now.



Here they are mounted on the back of the bag frame on my Brompton during a tour of the Netherlands




I made this randonneuring bag and seat wedge for my wife's bike. Here it is in France a few days before PBP. Despite this being a dry PBP she still got the chance to try out the water proofing the day before when I sat out in a soaking drizzle for 3 hours. Bone dry inside!



I made these hookless roll top front panniers for a short tour through Colorado last month (more about said Colorado tour, including lots more photos). I also made the randonneur bag, though it needs some tweaks, so I'll be taking it apart shortly.
