As of my last update in early 2023, the font "Paper" designed by Swimming Poulp isn't a widely recognized or specifically documented font in major typographic resources or font directories. However, based on the inventive naming and the creative force behind its nomenclature - Swimming Poulp (a "poulp" could suggest a playful take on the word "pulp" or a typo/misinterpretation of the word "pulp," relating to paper, or potentially hint at "polyp," suggesting versatility and multiple facets) - we can hypothesize and craft a descriptive illustration of what a font named "Paper" by this designer might encapsulate.

"Paper" might be envisioned as a font that embodies the tactile and visual textures of paper itself. It could feature irregularities and variations found in handmade paper, with a natural, organic feel. The font might exhibit slight variations in thickness and contour, emulating the way ink or pencil reacts to the physical texture of paper. Such characteristics would make it an excellent choice for projects aiming to evoke craftsmanship, authenticity, and a personal touch.

The style of "Paper" could range from delicate and fine, resembling lightweight, almost translucent paper qualities, to more robust and hearty, suggestive of thick, artisanal paper stock. Each style could serve different design needs, from elegant invitations and refined branding to more rugged, earthy, and sustainable product packaging.

Given the playful and creative spirit implied by the name "Swimming Poulp," "Paper" might also incorporate elements of whimsy and imagination. Perhaps there are versions or character sets within the font that play with the concept of creases, folds, or even tears, adding depth and narrative to the visual language it creates. This would make the font not only a tool for text display but a storytelling element in its own right, capable of adding layers of meaning to a wide array of design projects.

In conclusion, while "Paper" by Swimming Poulp as a specific font doesn't appear in the recognized font libraries or directories up to my last update, the conceptual exploration of its potential characteristics suggests a font rich in texture, adaptable in style, and infused with a playful creativity. It would be a fitting choice for designers looking to imbue their work with the nuanced, tactile essence of paper, bridging the gap between the digital and the handmade.
