I don't know what kind of technique was used to make the necklace
you posted, but it's probably a stuffed tube of some sort. It could
have been woven on e.g. a backstrap loom and sewn, with a seam that
doesn't show in the photo. Or it could be some kind of braid, etc.,
worked in the round. It doesn't look crocheted--that I would
probably recognize--but Tunisian crochet might give you the look
you're after. Most basic crochet books have instructions for this.
You might want to look at Beads, by Janet Coles and Robert Budwig I
don't have it available, but I remember that it does describe how
to make certain styles of ethnic necklaces.
Also, I know there must be many books that deal specifically with
braiding, twining, finger weaving, etc., , but the only book I can
think of right now is Arline Fisch's Textile Techniques in Metal
Her instructions are for wire braids, etc, but, since they
originated as textile techniques, the instructions should work with
cotton thread, of which the neckpiece you posted seems to be
Do we have members from North India who can identify the technique?
PS: I do remember, quite a while back, some very cool Tibetan fiber
technique being described in Bead and Button magazine--I see on
their site that it was for a closure and was in the June 2001
issue. You might want to check that out, too.
