The central area is barkcloth, made by beating a layer from just under the tree bark until it is thin and pliable.
Numbers 31-39 are of a new type for us, quilted from odd geometric pieces,
often with both sides equal in quality. (The barkcloth does not need hems
like woven material.) 31, 33 and 37 have raffia borders similar to those
on raffia skirts. We have not seen this form in any reference book and although
they are Kuba, we are not sure how, or if, they were used.
CARE: The cloths are not fragile (except for number 37 which has obvious
damage) and can be pinned onto a wall or panel for display, or framed like
a work on paper.
