I am more familar with the patterns from NorthWest Traders, so I was leaving this for people who might have some experience with that company or product. However, since nobody responded and that is not enough to answer the question to your satisfaction, I looked at the link.
What I see there are patterns that I generally would ignore on a bargain table. My reasoning is that I generally am Type A to the point where I would be reworking such patterns to the point where I might as well just draw my own.
"Flint & Gun Tool Wallet"
I folded a 6 X 8 piece of vegetable tanned leather and cut a few more 6 inch pieces to make flaps of varying pepths for each side and stitched this up along the edges to make a wallet. I stitched one side up the center and ran the stitches through a tie strap. The other side has more stitching to hold flints or small items. I looked at a wallet that an old guy made from a pattern and adapted as I wanted.
"Tomahawk Belt Carriage" and "Tomahawk Sheath with Sling Carriage"
I wrapped a piece of cardstock around a hawk head in various angles and the stapled the edges in various configurations until I got what I wanted. I marked instructions and laid the card over leather, adapted for the difference in folding between the two and stitched it all up. The sling version will not require a pattern so much as it requires a strap cutter which you can get from a variety of vendors. I suggest the wooden one as it works better than the more expensive metal one. Bees wax helps too.
"Rawhide Tobacco or Bullet Canteen"
My son knocked the cover off of an old softball and I folded one side against itself. I cut the small section connecting the two halves to form a bag pattern and then stitched through the old holes to form a pair of perfect .50 cal ball bags which are pre shaped to hold more balls.
(Ball bag here has a double meaning)
I made more ball bags of scrap leather and they were rather flat until they were filled with balls for a long time. I have since learned that some people use a similar pattern for such bags and use hot sand to get that rounded shape. I also see that some leather frosts the balls quicker than others, but they still work pretty well.
"Eastern Indian Pipe Bag"
I rarely smoke and would not use leather for this purpose. I would use something else unless I was sure of what was used to tan the leather. Fire, chemicals and breathing might be a bad combination, but I am funny that way.
"Woodlands Indian Knife Sheath"
Most patterns for knife sheaths are modern and you would be better served by looking up patterns from the web or making your own. I like mine deep and rounded.
"Canadian Cap"
I have no idea what this is, but if it is that Mongol cap pictured, I'll pass. But then, I am from the sunny South, so I might be a bit out of touch.
"Eastern Rifleman's Bag"
I have a couple of October Country bags and adapted the general design to make other bags for my various guns. I would just make my own. If I can, then surely you can.
In short, I have faith that you can do better without these patterns than with. This is likely the message that others were sending through their silence.
