Beware your arrows
Just a couple of general points for you, Annie, oh, and thank you, TT for that great research site.
Whatever the bow it should be well protected in a cover or case. You didn't ride about with it already strung unless you were about to shoot.
The bow string was kept covered, warm and dry. Usually in a pouch next to the skin. You never got it wet. Wet strings don't work well!
Arrow flights - the feathers - are quite fragile. A crushed or bent flight meant a ruined arrow that would not fly straight so you were careful about handling your arrows. This is why you see an archer about to nock and draw in the butts set hir arrows point down in the ground in front of hir.
A good quiver wasn't just a hollow container. It had a place for each arrow and a cover over the top as some means of protecting the arrows flights from rain or rough handling.
A good archer always carried a bundle of half made arrows with hir and the means to make new arrows from them.
The feathers for the flight for one arrow should always come from the same wing. You chose your feathers with great care.
Finally, (and I'll duck here as all the experts will start arguing because there are two schools of thought on this,) if you want your strongest people to use the long bow then remember this great bow had to be leaned into as you drew the string. This is why it was so hard to use. You actually bend the bow as you draw the string. And long bows and horse riding don't go well together. Give your riders small cross bows.
