Thanks to all the links, Q & A, and motivation from this forum I was able to finish my 1st frame bag. I've never sewn anything in my life, nore have I ever used a sewing machine. I'm mainly posting these pictures so that a noob like myself can get motivated and not be daunted by making your own gear. I used Cordera 1000 on the outside and Cordera 500 on the inside. I also added a 1/8" closed cell foam pad for the middle structure. I used heavy duty thread which seemed over kill and unecessary as it made sewing harder and caused me to break a needle, which may have been due to my lack of skill, but it seemed to screw up the machine if I did not have the thread in the right spot to start with. But seeing as I have nothing to compare the thread to I'm not sure if it was the cause or if I was.
I placed A 12" zipper on the top and a 12" zipper on the bottom....At the time this seemed like a good idea, but looking at it now, I'm not sure I need 2 zippers with such a small bag. I also added some zipper pulls which were easy and make opening and closing the zipper easier. The bike is a Gary Fisher size large, but for some reason the old 29er's had smaller triangles (this is my only 9'er so I have no comparison). The bag is 2.5" wide ( I think, haven't measured it officially since I placed it on the frame).
Overall this was a quick and fun project. Quick in the sense that it went by fast since I was learning a ton and I like arts n crafts. If you have questions and are considering making your own bag I'd be happy to help and tell you what worked and what didn't, more so what didn't since I had a lot of experience with that as I was constructing this.
Tools I used" sewing machine, cutting board, ruler, rotary cutter (which I swapped for scisors cause I couldn't figure out how to use the thing to cut through heavy duty fabric), card board for making a trace, chalk, and a thread ripper
