Query: Lastolite 78" Seems to be missing critical parts to me.

I was extreemly dissappointed with this for the price... It is just a thin fabric with velcro sleeves and no tubing or anything to make it stand up.... there is absolutely no way to use it. First time I've been unhappy with Lastolite but this one is useless.
