If you want shoots shafts, the typical materials where if course oceanspray and osoberry. Those are good heavy shafts. Dogwood was used but was not a favorite. Split timber shafts of cedar have also been found in caches.
As far as bows the flat and wide 'paddle bow' was the common style from California to SE Alaska. First choice was yew, and they would travel miles into the hills to get it, or simply trade there coastal good to the moieties who used yew as a trade item closer to the cascade range. a sinew backed yew bow was considered the cream of the crop. The second choice was purely up to the bowyer, or the one who was on the receiving end of the trade. The Siletz natives on the central coast of Oregon used yew, but Vinemaple was a very close second, even spruce was used for bows. Though there are no bows in tact, but it was thought that they would use salmon skin to cover there sinew. But only skin from the largest salmon, the chinook.
The back was usually painted with black paint and the belly red. Salmon eggs where used as a binder.
The more elaborate geometric painting came from down south (souther Oregon and Northern California)
As with most cases, the elders built the best and sweetest shooting bows. If a child showed talent at a young age they would then take an apprenticeship from the elder bowyer or craftsman.
And the same thing applied to those who showed talent for other things like jewelry and carving.
There many styles of this particular bow. Choosing which one you like is the hard part:)
My favorite one is made by the Makkah, Salish, and Kwakiutl. I have museum photos I will try and post later on today
