The technique of creating white-line woodblock prints, a one block method of print making, began in the summer/winter of 1915-1916 in Provincetown, Massachusetts.

Bror Nordfelt settled in Provincetown that summer and was joined by a group of fellow artists fleeing the war in Europe. This group worked together that summer and into the winter designing woodblocks using the traditional Japanese technique of one block per color, sometimes cutting as many as ten blocks for one print.

Nordfelt, becoming impatient with the laborious job of cutting so many blocks, experimented by cutting a "v" groove in the wood between the images. This "v" groove corresponds to the white line in the finished print. The paper is firmly attached to the block and each shape is painted with watercolor and is hand printed one shape at a time until the print is complete.
