Kathrin Wessel is a German illustrator and fabric designer working under the label Käselotti, based in Germany. She has been creating under this brand since 2007, initially producing handmade phone and tobacco pouches sold on DaWanda and at design markets before pivoting to custom fabric printing. Käselotti is built around animal illustration with a warm, inclusive ethos - every creature, from mosquito to polar bear, is rendered with friendliness and positivity. Sustainability in raw materials is a stated concern of the label.

The portfolio features a cheerful, character-led illustration style centred on animals in warm, approachable palettes. The work reads as family-friendly and playful, with strong line quality and a visual register consistent with kidswear and children's product markets. Expressions are consistently upbeat; the animal cast is broad.

Kathrin's practice spans illustration, sewing, and digital preparation for print-on-demand fabric production. Her background is deeply hands-on - she describes the practice as "Kopf, Herz und Hand" (head, heart, and hands). She also works as a children's book illustrator alongside the Käselotti fabric label.

Selected placements suggest product applications including fabric yardage and children's goods. Käselotti operates a direct-to-consumer WooCommerce shop stocking 200+ products. Category: kidswear.

Kathrin has been sewing, painting, and crafting since childhood. Käselotti launched in 2007 with handmade pouches sold on DaWanda and at design markets. After discovering fabric printing with her own motifs, the label evolved into its current form combining fabric, illustration, and children's book work.

Animal motifs drawn from the full animal kingdom - mosquitoes, jellyfish, polar bears - rendered in a cheerful, characterful illustration style. All creatures portrayed as equally sympathetic. The portfolio features all-over and scattered repeat structures suited to fabric yardage and kidswear.
