Kind of a fail....
The first frame bag I made for my road bike, it was a bit too big overall. I was so paranoid about it this time that I made it too small! I'm going to add an inch around the whole pattern for the next bag. The biggest need for me is getting my tent poles in the top of the frame bag and I messed up the zipper and they won't fit! I made a quick extender for the top strap and can put my poles in a bag and stow them there on top of the bag. That will work if I end up on a trip before I can make v2.0 of the bag.
I like the design overall and think it will work well once I get it sorted out. I will have to switch to sideloader cages, though.
Also, how wide are you folks making bags relative to your frame? My frame is about 2 inche wide, so I cut the spine at 2 1/2 inches to get the 2 inch spine. Is it common to make the finished bag a little wider than the frame or exactly as wide as the frame? Or is it a given that when stuffed, it will be a bit wider than the frame regardless of the spine?
