After seeing Erin Wassons Low Lov chains so many times, I decided to create some myself using some old necklace and bracelet chains. It was a little difficult for me at first because I think I'm stupid and unable to comprehend where the chains needed to go in order for it to work, but I got it down in the end.
All you have to do is make a circle with a few chains (size will vary depending on the size of your upper half)
Vertically connect the top and bottom of the circle to a middle chain in the front.
In the back, use another smaller chain to connect the two sides of the circle horizontally. It kind of looks like a butterfly when you lay it down flat not that that is even relevant...
That's it! It sounds pretty simple, but unless you have little scrap chains lying around, it can be a pain to rearrange them into a properly sized circle and whatnot. I suggest having tweezers on hand for readjusting.
