I find bast cordage fascinating and I thought I will put my study resources here for anyone to enjoy. Probably no-one
but at least I find them myself should I somehow lose access to my bookmarks.
Cordage in North America has good explanations on sinew vs. plant cordage.http://www.primitiveways.com/cordage_in_North_America.htmlAnalysis of the bast used by the Iceman as binding material, page 69.(Page 70 lists tree species useful for bast cordage):

"In the Mesolithic, cord has been recovered made from lime, elm, juniper, willow and rowan bast...
Historical records include the use of mosses, grasses, heather, lime, birch, hazel, beech, yew, pine and spruce...
The best bast is obtained from young trees cut in early summer,
though collecting it at this time implies a retting process lasting
several weeks, to degrade the soft tissues and separate the bast
from the outer bark. Bast can be processed more quickly in early
spring as the sap is rising, or in winter, in which case the bast can be
separated rapidly over a fire."
