A pair of meticulous moments. This fall, Jim Bachor has filled four Chicago potholes with flower mosaics ahead of his show next month at Packer Schopf Gallery. While studying art at Columbia University, Tammy Tiranasar stumbled upon a vintage 70s craft book and began making organic macramé necklaces akin to delicate drawings or even intricate mosaics like Bachor’s. Both artists send elaborate surprises out into the world. And perhaps ephemeral: the mosaics may not survive the scraping of winter. So scout them now.
