"Old Fashioned Chain" is the creation of Ms Bobbi Maw of http://MyWiredImagination.blogspot.com and was presented by http://JewelryLessons.com. I found this free tutorial when I was browing thru JL when I first started my wirework craft.
These are made with all the scraps of wire left that I had after a project. They're made with different gauges of wire, therefore you'll get a thinner or thicker chain. The wire is cut according to specified/required length, looped on both ends and then linked to each other.
These are good option if you do not have the ready-made chains available. Hmm.. I kinda like this chain, though.
Thanks for looking !
