[Northkeep] Longbow sinew string

[Gisela]

My "little angel" has done a very naughty thing which requires me to
purchase a new bow string. Can anyone help me with locating one and any
advise on what to look for? IE: length? I'd like to have one before GW,
although there will might be some available there. Oh yes, I also need
period arrows... any assistance would be greatly appreciated!!!
Danke!
