I hope no one takes this as criticism, but in all the cartridge boxes, cartridge pouches and bags I've made over the years, I've never used a cloth liner. I haven't seen evidence it is correct for an 18th or early 19th bag/pouch and that's the time period I have been concentrating more on in the last 20 years or so of my 40 plus years now of black powder shooting and reenacting. However, we have learned a lot since the early 70's on what is and what is not authentic and I've enjoyed seeing the sport improving in a more accurate historic portrayal.
Having said that, I still have natural curiosity on such cloth lined pouches. I have wondered if one makes a cloth bag and "tack sews" into the pouch or if the cloth bag is only attached near the tip of the interior of the pouch or if the cloth pieces are sewn into the seams/welts of the leather pieces of the pouch? I suspect one of the two first methods, but don't know for sure.
So I am looking forward to answers on this question as well.
