when i was in Sarawak in 2015 i sold a small collection of "yellowjackets". when i got back i realised i had none left, so just now in Tucson i was looking out for a few more examples.
On the short string in the middle are a few i found individually, and a long loop shown round the outside.
the types vary- there are:
1) a couple with wide apertures and red centres,
2) one or two with white then red, then yellow then black with yellow stripes,
3) and then again white central layers followed by red, white, black, yellow stripes...

the other string has all beads with narrow holes, red centre layers then white then black and yellow

they seem to have a slightly different red perhaps- and i wondered if those might be Chinese "tributes"?

Any ideas, anyone?
