D'oh!
Was setting up the seamless, realized I had ordered the wrong one but tried it out anyway (9' crossbar with an 8.9 foot roll). Had a client coming in 10 minutes..Two clients actually, one after the other and then another at 6. Had it set up perfect and went to go check my lighting bag..boom ! Look behind me and the stand gave way, falling through the seamless and ruining it...which unrolled..and unrolled...and unrolled.
Desperate and not sure what to do I managed to find a saw. The stand was okay, but the background was screwed. About 1/3 of it was ripped so I figured I would saw it down to use the other 2/3 and then be okay to use it for small portraits...sawed and sawed really fast...and then realized the inner tube was reinforced with a plastic middle.
"*#!*!"
So then I had a worthless seamless background, two stands and a crossbar laying everywhere..quickly ended up calling the first client and rescheduled for 2 weeks later, then the 2nd and the third.
Theoretically I probably could have unrolled the roll to the point where it wasn't ripped, then cut across the way to tear off maybe about 10 feet or so of the paper to use on the crossbar, rather than the whole thing.
Moral of the story: Don't make snap, creative decisions under stress involving sharp objects.
