What length of guylines for MYOG flat tarp?

I generally use a continuous rdgeline which may be as much as a 50 Ft, piece of 4mm accessory cord or as little as a 25 to 35 Ft. piece of Zing-It. The accessory cord doubles as a haul line or general purpose rope. If I’m pitching an A-frame using trekking poles, I often use pieces of braided nylon cord about 14 Ft. long, which I double and tie back to the ridge with a slippery half hitch. I will do the same thing for mid panel tieouts as well. My ground tieouts are about 3-1/2 Ft. long. In almost every case, I double them and tie them back to the tarp. The cord is small enough that it doesn’t weigh much and the knots are easier to reach. Another way is to attach short cords to the tieouts and carry loose cord of various lengths. Tie the loose cords to the tieouts with slippery sheet bends. The tieouts should be around a foot long and can be tied directly to stakes, if desired. Having the long cords loose allows you to change the tarp configuration without having to untie or move the tieouts. This also works pretty well when you are in a wooded area and want to rig a tarp as a fly.

Inadequate string is always a problem. The funny thing is, string weighs so very little for what it does.

I use 12ft ridgeline cords and 4 ft worth on the sides and corners.  I don’t have mid-panel points on my tarps so I can’t help you there. I tend to go a little longer than necessary just because it’s very, very little weight difference and having too short of a line is a pain.
