I have a DIY sil tarp I did a year or so back, and I want to trim it down in size a little. Currently it has a 12' ridge, and is approx 10' wide at the corners. I have never been super happy with my corners and ridge line reinforcements, and I would like it to be a little smaller. So, I thought I would trim the ends just enough to remove the ridge ends and corners, then redo them...but, it looks like that might bring it down to about 10'4" on the ridge. Is that going to be too short for my WBBB? All the tarps I see are 11', but seems a 10'4" should cover the blackbird enough for a warm weather tarp. Thoughts on this? Is 10'4" cutting it too close for coverage.
Below is a pic in its current condition.
