WCCC Dash Overlay Installtion

I am getting ready to install the new WCCC wood grain overlay onto my dash parts and wanted to ask if anyone has any new advice on how to form the overlay around the toggle switch holes? Is the bolt and washer method mentioned in the wood graining thread in the project forum the best or just using a socket to stretch the vinyl into the depressions? Thanks.

Received some good advice here on the project forum where I also posed the question.
