Invisible key 9

Leaves no ink - it only seeds the memory map.

What it does

The Invisible brush paints nothing permanent. As you drag, it adds to your drawing's memory and shows a brief glow where you went, then fades. Those remembered points stay - so when you switch to a connecting brush, its web reaches toward the paths you traced invisibly.

How to use

Press 9 or pick it from the brush menu.
Trace the structure you want the web to follow (a face, a spiral, a horizon).
Switch to Round and draw - connections will gravitate to the points you seeded.

Think of it as a guide layer made of memory instead of pixels: invisible scaffolding for the connecting brushes.

Try this Trace the outline of a face or figure invisibly, then lightly draw across it with Round - the web snaps to your hidden guide and the form appears out of the threads. Press m and Flash any time to see the scaffolding you've laid down.
