I really like all of the bags though the first really catches my eye. I too have read about how saddle stitching is where it's at though I haven't done it yet.
Maybe make a website or an Etsy store with business cards to pass out at gun shows. You also might want to talk to your local gun store as well. Maybe they'd like to sell your work.
LOVE the armguards! I'm an avid archer as well. I hunt rattlers for their meat, skin, and rattles. You've given me some good ideas. Since you mentioned you're looking for nice quivers you might want to check out Seven Meadows Archery if you haven't.
