Print out the design you want to transfer. Moisten the leather and let it sit for a few minutes until the surface is soft. Place the design on the leather and trace it to leave an imprint.
This is the initial imprint.
Use a swivel knife or scalpel to cut along the lines.

The swivel knife is then used to cut the leather to add more details in the clouds.
After adding oils and dyes, this is the finished design.
