Make a simple sketch that communicates on paper
A quick sketch can explain a table layout, poster idea or movement direction without polished artistic skill. Its job is to help another person understand, not to use every color.
Start with the largest shape
Draw the outline first, then key elements. For example, use a rectangle for a table and three circles for chairs. Leave space instead of filling every gap. Use one outline color and a second accent for the important part.
An image is not an editable project
PNG is raster and SVG is vector, as MDN’s format guide explains. Saving PNG preserves appearance, not the stroke history for later undo. Keep the page open until you finish editing.

Check the paper version
Inspect preview at a useful size, especially fine lines and colored marks printed in grayscale. Increasing print size does not add detail to a small image. This sketch is not a dimensioned engineering plan.
Example: a 1200 × 800 pixel sketch
At 6 inches wide, density is 1200 ÷ 6 = 200 pixels per inch. At 12 inches, it is only 100; the same file has gained no detail.
If crowded, remove an element or increase spacing rather than shrinking everything. Review a PDF or test print before distributing many copies.
