This is a quick process.

This uses 5 x 8 unlined note cards folded in half.

Start by finding a sturdy leaf.

Use a sharpened color pencil slightly on its side (practice rubbing parts of the leaf to achieve the effect you are trying to get).

Try different leaves and different color pencils.

I particularly like doing the rubbing up the center of the leaf. You can figure out what looks good to you.

You can also cut part of the leaf rubbing out and adhere it to the note card ( I use double-sided tape).

This achieves a different look. I also write a brief description in pencil on the back of the card reflecting my method, such as ‘relief rubbing of chestnut leaf with colored pencil’. It adds to the card’s character, and also provides the information.
