My mother mentioned she actually almost didn't buy the necklace for my birthday because she did not like the black heart pendant; it looked "tart." I told her I was already planning to change it as the heavy pendant wasn't correct for the lace anyway. I crisscrossed the chains near the center an moved the other chains around as well, making everything symmetrical. I would be irritated if it wasn't symmetrical.
Because the lace was two whole inches larger than my neck needed, and I didn't have the proper tools to shorten it, I attached nail polish coated 1/8 oz. lead fishing sinkers to the chain to drag it down my back. It works well! Detail:
