A personal watercolor paper laboratory

See what remains after the water leaves.

Paper Cast helps watercolor artists record how a sheet behaves while wet, return after it dries, and compare the two phases without relying on memory.

A repeatable studio routine
01Choose a paper from your stock.
02Describe the technique, water, and pigments.
03Log the wet observation without predicting the result.
04Return after drying and compare the shift.

Inside Paper Cast

Five views of the same material story.

Paper Cast keeps paper profiles, test sheets, observations, notes, and comparisons connected. The result is a personal record of how materials behave in your own hands, with your own techniques.

01

Bench

Start a new test, revisit fresh sheets, and see which dry reviews are due.

02

Sheets

Keep a searchable archive of techniques, pigments, water levels, photos, and phase-specific notes.

03

Stock

Organize paper by brand, weight, texture, cotton content, format, favorites, and your own tags.

04

Drydown

Compare wet and dry ratings for edge control, color depth, granulation, buckling, lifting, and surface fatigue.

05

Mixbook

Look across completed tests to find recurring patterns for washes, glazing, detail work, lifting, and layered corrections.

Private by design

Your studio records stay on your device. Paper Cast works without accounts, cloud sync, or a backend.

Built for observation

Wet ratings are never copied into dry ratings. Each phase is recorded separately so the comparison remains useful.

Your experience, not a verdict

Patterns are based on your own test history and presented as studio notes, not universal claims about a material.
