Without an abundance of hides at 1 time and collected over the years one can think exactly what he or she wants to make for themselves.
It's always a hesitating moment cutting out your pattern.Knowing full well how much time and effort you've put into the hide already and how soft and nice that it is.
But you'll get over that.Always keep your scraps of significant size.Many other things can be used or made from them.Small bags,lace,and sizes that you can bead or quill on to attatch to a garment.
For garments such as pants or shirts matching them according to their thickness is best.
I can tell you using white tailed deer especially bucks that are at least 4.5 to 5.5 years old is more than thick enough for pants.
Does of at least 2.5 years old are suitable for shirts.
Yearling deer of less than 1 year old and most pronghorn antelope or domestic goats are almost too thin to use,but have used them before with success and for other things also.
Holes that are made in the hide from broadheads are barely noticeable when properly sewn together while dressing and smoking the hide during the brain tanning process.Final sewing is done with real sinew before smoking.Real sinew will never break or unravel after drying.
They add character or tell a story IMO along with all the other scars.I tell how that is done properly in the "Big fella into Buckskins/Smoking/Lots of pics/Items made" on this same thread but about 10 pages back now.
