Cheap and very, very effective!

Even cheaper you will see a "scary room" for Halloween etc. can not set! The 100 grams are easily sufficient to transform a large hall in a single spider's web, as we know from science ficton, fantasy or horror movies and really everything wrap in thick webs.
But for that you need patience !!! This is not done in 5 minutes, then it just looks miserable and you can also batting on the windowsill clap.
First cuts you a little, about walnut large piece from the bale out and find yourselves a stable first anchor point (a nail, a hook, a curtain gas station - a small notch in the wood, a heating pipe - you will see, each room has countless such possibilities) , Pulls the fabric a bit apart until you recognize where there is a particularly strong and good to be renewed connection. Attracts them to a second fixed point - the little tissue can be loose with a little sense to many meters pull apart.
Now you have a basic axis which is also applicable to three or four axles (always at fixed points) extend. The magic begins with the minor axis. Draws from the long, sinewy basic axis a few fibers as to form a triangle out - and already forms the "network". This third point is so real and so easy - it can also be provided with a strip of adhesive tape attached to the smooth wall in the middle and holds sensational - well over METER!
Urgent typing Works not "flat", which acts often wrong - but in three dimensions, and cross qreuz. Take your time - really every point of your backbone, which "acts as cotton thick" still has potential, again pulled in new directions to werden- one more time through an old weave through etc. After 5-10 minutes you have the first "walnut "processed and already several cubic meters of your room" cocooned ".
Who takes two to three hours, absolutely reach Hollywood grade horror effect, as if giant spiders just around the corner (..as in Stephen King's "fog" film ...!) - Make fun and do that too.
And the best part: It's no fraying cotton! When cleaning up your pact the fantasies easy, pulling it off and you're done, they usually pull the Tesa equal with the wall. In 5 minutes the whole nightmare is over and in the tub (unfortunately recycle not really possible, which then no longer looks, since the voltage of the nets is missing and everything sags)
