I finally got around to making my own version. I started by soaking a piece of lace from my stash in warm water. I covered my work surface with plastic, then sponged the dye straight from the bottle on the wet lace. I used the goldenrod and brown dyes, but the brown looks more like indigo once it dried. I had used this dye once before on the trim for this robe and it turned out a much deeper color, so I think this particular lace may have some poly in it. These dyes are really nice to work with because there's no mixing, heat setting or foul odors.
Once it was dry, I sewed two rows of beads along the length of it. I think I would have preferred smaller, more sparkly beads but these purple-brown and gold beads were the only ones I had that went with the finished color.
I am not a very elegant Frenchwoman, but I do have a pretty cool scarf-neck-lace.
