Having seen Sarah Millsop demonstrate making these, I was inspired to have a go. Basically shamballa style bracelets but made with 6mm spacer beads.
The one on the left was my first attempt, and I realised that I had inadvertently cut a length of the narrower cord for the knotting cord. The one on the right is made with the correct thickness. However, people that have seen both say they really like the one on the left, as it is very delicate. It would be ideal for kiddies bracelets.
I also experimented by adding a bead to the fastening piece of macrame. Must confess I rather like that, and shall do it again.
