I know it likely was frustrating to work with... but man, you can't argue with that result! Looks really great (and LOVE the webs!) 
The first of 4 30' strands took about 2-3 hours, but after discovering the technique, it was down to 30-45 min per strand. Hook tightly over doorknobs and heavy chairs, moving to maintain tautness.The spider looks great, but the your web is amazing. How long did it take to lay that out and cut all the holes?
No instructions. Anything you can use to stretch as tautly as possible. We took a brief video: https://youtu.be/41EFSfndJxkMay I ask where you ordered it from, and the size?
Also is there a guide for beef netting web? you mention chairs and such.
