Doppler PDX is a gallery/studio promoting dialog around experimentations and processes that artists undertake while creating their work. Press release:

Constrain to Vertical is a show by Brenda Mallory where she creates works inspired by stacks of UPS “end-of-day” barcodes. Mallory used a sewing machine to sew sequential lines (or pintucks) in fabric wall pieces. Drawing from the minimalist paintings of Agnes Martin, Mallory utilizes vertical line on the fabric. As she confined herself to work within strict linear parameters, Mallory work moves outside of her norm of organic form. Constrain to Vertical is an exciting new direction for Mallory and her work.
