Version 1.0.0 · Draw, undo, and compare pen exercises.
Make the marks yourself. Build light and dark areas with lines or dots, compare their spacing and direction, and keep a drawing or blank practice sheet for the next session.

What to practice
Explore how mark placement changes a value or describes a surface. Measurements report properties of the marks you made; they do not turn a pen exercise into an artistic rating.
How to use Hatching & Ink Studio
- Choose a technique and inspect the sample and target area. Read whether the task asks for lines, dots, changing line weight, or a particular direction.
- Choose your pen width and ink color. Draw in the practice area with a mouse, finger, or pen; switch to page scrolling when you want to move around the page.
- Use Undo and Redo to revise marks. Choose Measure my marks to inspect the measurements relevant to this exercise, then compare with the example.
- Record what happened when you changed spacing or direction. Download the current PNG, print a blank sheet, or explicitly save a backup containing your current marks.
Frequently asked questions
Do I need a pressure-sensitive pen?
No. A mouse, finger, or ordinary pointer works. Use the Pen width control to choose thickness when pressure information is unavailable.
How are lines and dots measured differently?
Line exercises can report a line count and direction difference when the task has a target direction. Dot exercises count dots and inspect coverage; they do not receive a line-direction score.
What does ink coverage mean?
Coverage estimates how much of the target region is touched by the rendered marks. It is a geometric description of this exercise, not a judgment about whether the drawing is attractive or expressive.
Can I use this on a phone without drawing while scrolling?
Use Draw in the practice area when you want to make marks. Switch to page scrolling to move through the page. The control makes the current interaction mode explicit.
Can I undo clearing my marks?
The current lesson keeps an undo history, including a confirmed clear action. Download or explicitly save a study if you want to retain its current marks after closing the tab.
What can I use for paper practice?
Choose Blank Practice Sheet for a printed drawing area or Step Sequence for the lesson stages. US Letter and A4 are available through the browser’s Print / Save as PDF dialog.
