I like #2 because the lavender 'floats' the embroidered squares before starting the darker colored borders. It's a nice extension of the finishing triangles, which I think is necessary. Otherwise, the lavender triangles are sort of an afterthought. I think I would make the next border white and the final border the same purple as you used in the center of the quilt. I always try to use the same colors in the border that I have used in the quilt - or I use a print that has similar colors.
