<p><em>Acute Angles</em> is a sister volume to <em>We Said Hello and Shook Hands</em>, which appeared in 2015. That volume presented over 500 collage collaborations between Zach Collins and over 100 other collage artists, in which one artist&#39;s "starter collage" would be completed by one or more collaborating artists. However, some of the "starter collages" that Zach put together seemed to want to stand on their own. <em>Acute Angles</em> is a selection of those elegant, simple works, speaking quietly but with a clear voice.</p>
