After sleeping on it, I realized that the problem with the eternity-heart motif wasn’t the motif itself, but the spacing. I had been threading up straight draw, and as a result the pattern repeated every half-inch, crowding the motifs together.
Unfortunately there was no way to do both the knot and the heart in 24 shafts and still leave 4 shafts left over for the broken twill background, so I eliminated the heart (heartless me) and went with the eternity knots, spaced about 1″ apart. I like this a lot better:
Again, you’ll have to zoom in to see the eternity-knot pattern.
I like this a lot more; it’s not nearly as distracting. And it leaves room for embellishment (beads anyone?) should I decide to go that route. I could see pearls or small crystal hearts or gold beads. Or nothing at all.
