If you are in situation that you need to work on skateboard design this template might be very useful. I've decided to share it because I've spent a lot of time searching one that is accurate, couldn't find it, so I created one.

There are four layers:
1. Base
2. Artwork
3. Clipping Mask
4. Holes.

Idea is to keep locked "Clipping Mask" layer and after you finish with design, unlock "Clipping Mask" layer select everything and create Clipping Mask (ctrl+7 if you are using AI). Also, "Holes" layer should be left on top of everything.
