We thought we’d seen black and white manipulated and stretched and combined in every way possible. Then UK’s Carol Blackburn took another look and came up with this Barcode necklace.

It’s made of her hollow tetra beads, dimensional shapes that remind me of small cream containers and fancy tea bags.

So not only are the striped patterns confounding, but the shapes add another layer of difficulty. The most magical thing is that her methods are actually elegantly simple. Here’s hoping she adds this to her upcoming classes.
