creating texture

I wanted to create the texture on my clay slabs by pressing the leaves from my site onto the slabs but since collecting the fallen leaves a few weeks ago they have dried up. They are now too dry to peel open to reveal the texture of the inside. So, I fired my original texture cube and then am going to press that texture onto a new small slab and fire it in order to use this as my tool for creating texture. I found this video that has the idea of making the texture on a hollow log shape in order to continuously roll the texture on the slabs. This would address the issue of what to do with the sides of the slabs and how to make the sections of the texture work together.
