T-top canvas replacement

[Scott1115]

I plan to remove and replace the old torn and leaky canvas with new. Where the antennae and radar wires go through the canvas I will need to make holes. What should I use to make the holes and is there anything special I should do to prevent the new canvas from tearing in these areas after the holes are made? Plan on using Sunbrella (or similar) material.

Thanks,
Scott
