Quick answer

Pull off a palm-size tuft, flatten it, then stretch it slowly from the center outward with spread fingers, hooking the edges on corners, rough surfaces or small pieces of tape. Thin, see-through webbing covers the most area: a pack with 10 sq ft of stated coverage fits a compact accent such as two upper door corners or a 2 x 5 ft patch, and about half that if you want dense, cottony webbing. Keep it away from candles, hot bulbs and heaters, and outdoors use it only in dry, covered spots.

Stretch fake spider web in small, palm-size pieces; stretching a whole pack at once tears it into clumps.
Stated coverage, such as 10 sq ft, assumes a thin, see-through spread; as a planning cushion, allow about twice as much webbing for a dense look.
Webbing stays put by snagging on rough surfaces and corners; on smooth walls and glass, small pieces of tape hold the edges.
Fake webbing should be kept away from open flames, candles, hot bulbs and heaters.
Outdoors, use webbing only in dry, covered spots and keep it close to surfaces so it doesn't snag birds or other wildlife.

Work in small pieces. Tear off a palm-size tuft, flatten it, and stretch it slowly from the center outward with spread fingers, turning it as you pull. Then hook the edges onto corners, rough surfaces or a few bits of tape. The thinner you stretch it, the more area it covers and the more it looks like a real cobweb; dense, cottony patches use up webbing fast.

How much area does one pack of spider web cover?

Coverage on a package is a stretched, see-through figure. The Olen stretch spider web with 2 spiders, for example, states 10 sq ft, which suits a compact accent rather than a whole room. How far it actually goes depends on how thin you pull it. As a planning cushion, allow about twice the webbing if you want a dense look.

Spot	Typical size	Approx. area	10 sq ft packs, see-through	10 sq ft packs, dense
Two upper corners of a doorway	2 x 2 ft each	8 sq ft	1	2
Window corners and top edge	Partial 3 x 4 ft window	6–8 sq ft	1	1–2
Covered porch corner	3 x 3 ft	9 sq ft	1	2
Stair railing	10 ft long, 1 ft deep	10 sq ft	1	2
Bookshelf front	3 x 6 ft	18 sq ft	2	4
Table centerpiece	1 x 4 ft strip	4 sq ft	Part of 1	1
Basket, wreath or lantern	Small accent	1–2 sq ft	A few tufts	A few tufts

Planning estimates only. Density is your choice, and real coverage changes with it.

Step by step: stretching fake spider web

Before you start

Decide where the web will hang and find two to four anchor points: door and window frames, the corner where two walls meet, shelf brackets, chair backs, railings. Clear away anything hot. Fake webbing is a loose mass of fibers, and it should never sit near candles, jack-o’-lantern flames, fireplaces, space heaters or hot bulbs.

Pull and flatten a small piece

Tear off a tuft about the size of your palm. Press it flat between your hands and tease it with your thumbs into an even pad. Hard knots don’t stretch; pull them apart now or discard them.

Stretch from the middle

Push the fingers of both hands into the center of the pad and pull outward slowly. Turn the piece a quarter turn and pull again, so it opens in all directions instead of one long rope. Stop when you can see clearly through most of it and the holes range from about coin-size to fist-size. Yanking quickly tears the fibers into clumps; slow and steady pulls give long, fine strands.

Hook the edges

Stretched webbing clings to anything with texture. Catch the edges on corners, wood grain, brick, plants, rough fabric and the edges of frames. On smooth paint, glass and plastic, press the edges under small pieces of painter’s tape where they won’t show. Pushpins work on corkboards and wooden frames. For tips on what won’t mark painted walls, see the guide to hanging decorations without damaging walls.

Add strands and layers

Real cobwebs have long guy lines. Pinch a few fibers at the edge of your web and draw them out to a nearby anchor, like the spokes of a wheel. Then lay a second, thinner piece over any sparse patch. Layering two thin pieces looks more natural than one thick one.

Place the spiders

Tuck spiders into the strands slightly off center and near eye level, where guests will notice them. The Olen web includes two black plastic spiders; a small dab of mounting putty on the underside keeps one in place on a vertical web.

Common mistakes and quick fixes

It looks like a cotton ball stuck to the wall. The piece wasn’t stretched enough. Pull it off, open it up from the center, and re-hang it thinner.
It sags into a hammock. There are too few anchor points, or they’re too far apart. Add a strand to a third anchor near the low point.
It all looks flat and even. Real webs are uneven. Leave some areas nearly bare, make one or two denser patches near corners, and vary the length of your strands.
Strands keep falling. On smooth surfaces, the fibers have nothing to grip. Add a tiny piece of tape at each anchor, hidden behind a fold of web.
You ran out halfway. Thin out the webbing you’ve already hung and spread it further before opening another pack.

Lighting a spider web display

White webbing stands out most against a dark background or with light coming from behind or from the side. A battery puck light or an LED string placed a safe distance away throws the strands into relief without adding heat. Some white webbing glows under a black light, but not all of it does, so test a small piece before you build a scene around that effect.

Indoor ideas that use one pack well

Doorway corners: two triangular webs in the upper corners of a front or bedroom door frame make a clear entrance with very little webbing.
Window corners: webs in the top corners look good from inside and out, especially with a light behind them in the evening.
Bookshelf or cabinet: drape thin webbing between objects on one or two shelves rather than across the whole front.
Table accent: stretch a thin layer around candlesticks only if they hold battery candles, never real flames. Keep webbing off any surface where food is served.
Focal point: pair the web with one bold prop, such as the 22-inch bloodshot eyeball foil balloon, hung or placed at the center of the scene.

Using spider web decorations outside

Webbing is happiest indoors. Outdoors, use it only in dry, covered spots such as a porch ceiling corner or under an overhang, and bring it in before rain, heavy dew or strong wind; wet webbing mats into soggy clumps that are hard to remove from railings and siding.

Keep outdoor webbing close to surfaces rather than stretched across open air, bushes or gaps. Fine strands in open spaces can snag small birds, bats and insects. Take outdoor webs down after Halloween instead of leaving them up for weeks.

Safety around kids and pets

Keep plastic spiders and other small parts out of reach of young children.
Hang webbing above the reach of pets. Cats in particular may play with or chew loose strands, which they shouldn’t swallow.
Keep webbing away from all heat sources and open flames, including outdoor candles and string lights that run warm.
Let an adult do the setup, especially anything that involves a step stool.

Taking it down and reusing it

Roll the web from one edge toward the center so it gathers into a ball instead of shedding strands. Peel off any tape. Lightly stretched webbing can be stored loosely in a box and pulled out again next year, though it tangles more and covers a little less the second time. Heavily stretched strands and anything that got wet are usually easier to replace. Store spiders separately in a small bag, and keep everything in a dry place. More seasonal pieces are in banners, garlands and decorations.

Step by step

Plan your anchor points
Pick corners, frames, shelf edges, railings or furniture where the web can hook on, and move candles, lamps and heaters well away from the area.
Pull off a small piece
Tear off a tuft about the size of your palm rather than working with the whole pack.
Flatten it into a pad
Press and tease the tuft with your thumbs until it's a flat, even pad with no hard knots.
Stretch from the center out
Push your fingers into the middle and pull slowly in several directions, turning the piece as you go, until the holes range from coin-size to fist-size.
Hook the edges
Catch the outer edges on corners and rough surfaces, or press them under small pieces of painter's tape on smooth surfaces.
Add strands and layers
Draw thin strands from the main web to nearby anchor points, then lay a second, thinner piece over sparse areas.
Place spiders and accents
Tuck spiders into the strands at eye level and off center, and add a focal prop nearby.

Frequently asked questions

How much area does one pack of fake spider web cover?

Go by the stated coverage, such as 10 sq ft, but treat it as a thin, see-through figure. That's enough for two door corners, a covered porch corner or a short stair rail. For a dense look, plan on roughly twice as much webbing.

Why does my spider web tear into clumps instead of stretching?

You're likely pulling too large a piece, or pulling too fast. Work with palm-size tufts, flatten them first, and pull slowly from the center in several directions.

How do I make fake spider webs stick to a smooth wall?

Webbing clings to texture, not to smooth paint or glass. Press the edges under small pieces of painter's tape, or anchor them to the door frame, window trim or nearby furniture instead.

Can I put fake spider web outside?

Only in dry, covered spots, such as under a porch roof. Bring it in before rain or wind, keep it away from heat and flames, and keep it close to surfaces so it doesn't catch birds or other wildlife.

Can I use spider web decoration on a basket or wreath?

Yes. Stretch a few small tufts thin and hook them over the weave or the wreath frame. A little goes a long way on small pieces.

Can I reuse stretched spider webbing next year?

Lightly stretched webbing can be rolled up and stored in a box, though it tangles more and covers less the second time. Webbing that was stretched very thin or got wet is usually better replaced.

Is fake spider web safe around pets?

Hang it out of their reach. Pets, especially cats, may bat at or chew loose strands, and swallowing fibers isn't safe for them.
