Below is an example of a necklace I made using the Kumihimo technique but on a card (click here to read more about this and a search on Google will find many more examples - Shirley Berlin's Green book is excellent) and not a Marudai stand (click here to read about the Marudai). Once I'd made it I knew it would need a special bead and was lucky to find a heart-shaped bead with a big hole in it so I could thread my braid through.
As you can see I also have a small collection
of heart-shaped beads, in fact I have quite a few!
One just has to have a stash of stuff ....
