There is no way I would be able to complete it in time, but if I made this pattern I would use two different colors for the center spirals. And probably use a different border color for each one.
Of course the pattern would have to be done twice before it repeated.

It is fastly done. I only needed 4 hours, spread in a day...

I might do one that way, EdBlair. I have some colorschemes in mind, but I didn't start it yet.

cool idea, EdBlair :) you can make it anytime! :)

It needs two changes in the knot-structure though ....

Actually for what I have in mind the only knot that needs to change is the middle knot in Row 11 should change to a forward knot.
I'm starting a different bracelet now. I might come back to this one later.

Knot 5 in row 24 is the other knot I'd like to change :-)

My plan is to have both strings in the knot in row 24 be the same color, so the change would not be visible. I might automatically (and silently) change one of the "black" knots in that row for symmetry.
In row 11, I would be using two different colors for the two "black" strings, so the knot change is necessary for my implementation plan.

This contest is closed now, the voting has started.

Mine is uploaded now, with both changes since I can't win anyway, being a moderator:-)
