A very quick addition to the Tarp Fastener uses. Tonight I wanted to take another long exposure shot inside the car and have a bit of fill flash on my face.  I wanted to place the strobe on the dash and initially thought I had nothing to secure it to. It’s a sloped dash, nothing that’s just placed on it stays put.  Then my eyes came to rest on the air vent. One fastener loop passed loosely through the vent was able to snag the next one pinched together and pushed though the adjacent slot. Gently pulled tight the first one threaded the second back though and hay-presto I had a securing point for the flash!
