I've recently come across a lady who lucets braids. I met her at a craft fair.
She demonstrated it to me on her fingers, but it actually has it's own unique tool, and is described as a form of French knitting, but it's traceable back to Viking, and possibly Roman times. See http://m.youtube.com/watch?gl=US&hl=en-GB&client=mv-google&v=OPspr81RBVk
for demos, and http://www.thelucet.co.uk/lucet_vocabulary.htm
for some very ornate braids on an adapted lucet. (Sorry, my phone won't post embedded hyperlinks).
I also picked up linked videos for finger-crochet, and then I noticed this:
Nalbinding, also known by several other names, including naalbinden and needle-hitching. But I haven't seen as many types of 'stitch' listed for needle-hitching in Stewart Grainger's Ropecraft as there apparently are for nalbinding.
Are there many similarities, or many differences? I note that nalbinding is specifically done with 'short' lengths of cord, rather than a continuous length.
