Finally finished my blackcat-type tarp made from black silnylon and reinforced with the remains of the camo nylon I got from Barre's bargain bin. Got the seams sealed this weekend. Hung it in the garage on a super windy day and it seemed to hang in there real nice. Wasn't sure how long to make the lines so I did 6 feet, what length do you all use? Can't wait to give this a whirl.
