Based in London, England, Kapitza is a design partnership formed in 2004 by Petra and Nicole Kapitza, focusing on book design and illustration, as well as art and exhibition work. Their first pictographic font, Blossomy, consisted of 72 flower and plant illustrations, which was followed by numerous outline fonts and collections of vector images. The latter typically start as photographs that the sisters then use as the basis for hand-drawn outlines, which are made available in PDF vector format. An earlier example of this is the We Love Nature illustration set, which includes the Blooms, Stems, Leaves and Flowers collections.

Kapitza's latest release is Herbarium, the inspiration for which came from an 18th century herbarium. This time out the sisters explored the fundamental structures that shape nature and came up with stylized forms to express this, the result being imagery that differs from the more realistic earlier releases. Herbarium includes Twigs and Branches, together providing 167 illustrations that can be used as-is or combined and modified in the image editing or vector illustration app of your choice.
