video How to Tie a Spider Web
Here's how you can create a giant Spider Web using rope and a frame with 24 eye bolts. You can use this technique to weave a spider web at any scale, as long as you have an even number of at least 24 points to fasten to, around four sides.

In this video, I used 200 feet of 1/4" rope and a strong-but-lightweight frame I built with four sections of 3"-diameter PVC pipe from a hardware store. (You can use larger PVC pipe or wood.

Materials Needed (as shown):
(Metric conversions shown on video.)

4 7-foot lengths of 3-inch PVC pipe
4 3-inch PVC pipe elbow joints
20 3/8"-diameter x 3-inch long eye bolts
4 3/8"-diameter x 4-inch long eye bolts (for elbow joints)
24 washers, 1&1/2"-diameter with a 3/8" hole
24 locking nuts (with the plastic liners)
PVC pipe cement (if you cement an elbow to each pipe, you can disassemble your frame)

Rope: two 50-foot lengths and one 100' length of 1/4-inch solid braid cotton sash cord (clothesline)

Tools:
Power drill with 3/8"-bit
Wrench
Scissors

This piece requires about two hours to tie.

You should wear a spiderman costume for this one! :D
or get a manequin head from the dollar store, put the web at your window, along with the head on the windowsill with a spiderman mask on it

Didn't realize it was. Thanks. Sorry I saw this only after Halloween.

This was awesome. Thank you for posting it. I ended up buying 4-10ft lengths and making 2-5x5 webs. I also found some glow in the dark rope that is neon yellow so you can see it during the day and it ads a little glowing sumpin sumpin at night. Once you get the knots down, the whole thing goes pretty quickly.
