I’m making a truss to hang a huge American flag on, on the ground, then hoist it up in front of my garage door. In the past I’ve done it with like 15 tarp clips and braided fishing line but i gets all droopy and is a pain to move along behind the flag on a tall ladder attaching them individually. I’ll drape the top edge of the flag over the truss but is there something good to use to clamp the flag to the 3/4” pipe? Best thought I have so far is buttons and button-holes or maybe stage light C-clamps.
