rings, that I found on ebay, and added some knot work to them.
I tied Spanish ring knots on the grooved spinner and classic grooved rings, and added a Gaucho knot to the chunky one.
The grooved sections help keep the knot work from sliding off the rings.
I used 0.9mm cord, black and orange that I had, and used a blue Sharpie marker to color a couple of feet worth of white cord. A coat of brushed on super/krazy glue was added to the Spanish ring knots, none on the Gaucho knot.
The photo of the rings without the knot work shows a cigar band(flat) ring at center, that I received initially in error, but the seller later sent the correct grooved ring.
I haven't added anything to the flat ring yet, and if I do, I imagine a bit of super/krazy glue would help secure knot work in place.
I gave the blue and orange one to my dad for an early birthday present(Dec. 24). Go Auburn! War Eagle!
