These patterns are essentially variations of each other; the hearts are all the same. The squares in the photos all have their ends worked in, so the edge warps and wefts of each are doubled. When I use two colors the warping scheme is L1-3/4 unless otherwise designated.

I wove two samples for this square because I wanted to compare them. In the first sample I think the heart stands out and the frame gets lost. In the second the heart still stands out, but the frame shows up a little better. It might be interesting to try this same pattern with L1/3-4 and also L1-2, 4/3 warping. Overall, I think I prefer version 1.
