I have a 9 1/2 inflatable roll up that I haven't used for a number of years. I had repaired some small holes in the past and am pretty familiar with what needs to be done. When I pulled it out of my outdoor shed where it's been residing, I was alarmed to see that some of the outdoor critters had a feast. There are now at least three holes chewed out roughly 2-3 inches in diameter. I'm willing to try and repair them myself but would like some input on whether there is a different technique to repairing larger holes than smaller ones. Any other precautionary notes or advice?
