A background should sit behind the text, not in place of it. This paragraph lies on the tile at its true scale — if it reads without effort, the tile can go under content.
Thin dark-brown outlines of rounded squares, trefoil shapes, teardrops and small triangles sit on a tan ground, with a square motif at the center of each repeat flanked by blob-like forms and scattered small figures. The motifs recur in a regular grid, with the larger squares and blobs forming a staggered rhythm across the page.
