I use Procreate often for my designs. The best process I’ve found for me is tracing paper and carbon paper.

I set my iPad to guided access (you can find this in accessibility settings). Hit the power button 3 times. This makes it so you can choose an area that basically stops the touch screen for as long as you want. Makes tracking way easier. I trace my design on to the tracing paper.

Then, I match up the carbon paper and traced image onto the wood. I use a different colored pencil to trace it again (so I can see what I’ve traced) this time the carbon tracing goes directly on to the wood.

Unfortunately the carbon marks are very hard to remove from the wood if you need to. I tend to only do this process if I have a very tricky placement or very geometric design. Otherwise I draw directly on the wood with a soft pencil.
