How to repair a hole thru linoleum and plywood?

I think, first off you should sit down and grab a beer. This doesn't look to be as bad as you initially described it. After you've calmed yourself down from beating yourself up, I want you to repeat after me, "I will not store my fast guns inside my TC anymore!"

You've got some great pointers here on the repair. Once it's finished you'll not notice it again. I wish I could repair some of the things I've done in the past as easily as this will be. Good luck
