Most fursuit makers who build bodysuits will ask for a duct tape dummy before they cut a single piece of fur. It is a rigid tape shell of your body that the maker stuffs, mounts, and drafts your pattern on, which is why Star Fursuits describes it as the thing that makes a custom fit possible at all.
It is also the single easiest part of a commission to get wrong. Makers reject dummies every week, and a rejected DTD means you re-do the whole afternoon and your slot moves back.
This guide covers the supplies, the method makers actually ask for, and the specific mistakes that get a dummy sent back. One rule outranks everything here: your maker's own DTD sheet wins. Makers disagree with each other on real details, and the sections below say so where they do.
A duct tape dummy is a body double. Your maker re-seams the shell, stuffs it, and builds your bodysuit pattern directly on a copy of your torso length, your shoulder slope, and your thigh shape. A measurement list cannot capture any of that.
The fit consequences are physical, not cosmetic. Beetlecat's sheet is blunt about it: the groin and underarms need a tight fit or the resulting bodysuit loses range of motion. That is the difference between a suit you can dance in and a suit that fights you every time you lift an arm.
Two timing rules come up repeatedly. CityMutt warns against reusing a dummy older than roughly a year, because an outdated DTD can produce an unwearable suit. Blue Harbor goes further and asks clients to make the DTD only when the maker requests it, rather than having one ready in advance.
Duck Max Strength Duct Tape 6-Pack
DuPont Tyvek 400 Disposable Coverall
Madison Supply EMT Trauma Shears 7.5in| Item | How much | Why it matters |
|---|---|---|
| Duct tape | 3 to 6 rolls | The structure itself. CityMutt's rule of thumb is one large roll per 50 lb of body weight. |
| Painter coverall | 1, sized up | The sacrificial base layer. Buy it oversized so it reaches your wrists and ankles. |
| Blunt-tip shears | 1 pair | Trauma or bandage shears. The only safe way to cut a shell off a person. |
| Permanent marker | 1 | Cut lines, registration marks, landmarks, your name. |
| Plastic bags or wrap | a few | Covers hands and feet so tape can run past the coverall without touching skin. |
| Paper towels | a handful | Bridges the gap at wrists, ankles, and neck. |
| Helpers | 1 minimum, 2 better | You cannot tape your own back or cut yourself out. More helpers means a shorter session. |
Buy name-brand tape. Blue Harbor names Duck Brand all-purpose silver. The Fuzz Factory warns that cheap tape will not stick well, and separately recommends against Scotch tape because of the smell it leaves behind. Eastern Dragon specifies a non-stretchy cloth tape and names Gorilla. Stretchy or thin tape sags, and a sagging shell is a wrong pattern.
Consider two tape colors. The Fuzz Factory and Beetlecat both suggest making the second layer a different color from the first. Gaps and thin spots then announce themselves instead of hiding.
Wear what you will wear under the suit. Beetlecat asks clients to put on their binder, cooling vest, or any body-mod pieces before taping, so the shell matches the body the suit will actually go over.
Never make a duct tape dummy alone. A DTD is a sealed, non-breathable shell around your torso and limbs, and you cannot safely cut yourself out of it. You need a second person present for the whole session: someone who can cut you out immediately with the blunt-tip shears if you feel faint, overheated, short of breath, or panicky. Keep the shears within their reach from the first strip of tape, take breaks, and stop the session the moment you feel unwell. Do not push through it.
Budget one to three hours with one or two helpers. Eat first, hydrate, and use the bathroom, because you are not getting out of the shell quickly. Shower beforehand as well: several makers, including Foxes in Boxes, list unpleasant odor as an outright rejection reason, and whatever you smell like goes into the tape.
This is the rule the draft version of every DTD gets wrong. Tear strips roughly four to six inches long and place them on the body in an overlapping criss-cross pattern, with each strip overlapping its neighbor by half an inch to an inch.
The Fuzz Factory describes the correct motion precisely: grab the tape near the body, unroll more tape, then set it on the person. Never pull the tape directly onto the person, because that tightens it. Wrapping a strip straight off the roll and around a limb does two bad things at once. It squeezes you smaller than you are, so the suit comes out undersized, and it produces a weaker shell that deforms in the box.
Start at the groin and underarms, then work outward to the torso, the legs, and the arms, with the hands and neck last. Those first two areas are the only places where makers ask for a genuinely snug fit. The Fuzz Factory calls the target "comfortably snug, like a pair of socks" and notes that a baggy crotch will show up in the final suit.
For the torso, stand straight. Slouching during the torso pass makes the front of the finished suit too short, a mistake both CityMutt and WildFox Works call out.
For the legs, feet about shoulder-width apart, knees relaxed and never locked. Locked knees are a fainting risk when you are standing still inside a non-breathable shell for two hours.
Arms horizontal at shoulder height, palms down. The Fuzz Factory notes that anything lower creates sizing problems. Foxes in Boxes and Blue Harbor both list an A-pose, or arms hanging at the sides, as grounds for rejection and delay.
Holding a T-pose for that long is genuinely hard, which is why The Fuzz Factory suggests resting your arms on floor lamps or similar props. Set them up before you start taping.
Tape past the wrist bone, down to and over the heel, and up the neck. Beetlecat asks for coverage to the base of the thumb and partway up the hand. CityMutt lists stopping short of the wrists and ankles as a cause of short arms and legs on the finished suit. WildFox treats the neck as optional, so check your maker's sheet.
Build at least two full layers, ideally three. Blue Harbor's standard is explicit: no holes, no weak spots, no thin spots, and no coverall fabric visible except at the very edges.
An unmarked dummy is unusable, because your maker cannot re-seam it in the right position or find your proportions on a stuffed shell.
Draw the cut line your maker specified, then add registration marks: short lines perpendicular to the cut, every four to six inches along it. Foxes in Boxes describes these as X's crossing the line. They let the maker line the two halves back up exactly.
Then mark, at minimum:
Blue Harbor also asks for an email address on the dummy itself. If you want a crotch zipper, Foxes in Boxes asks you to mark where.
Use blunt-tip shears, and slide a finger under the tape ahead of the blade so the metal never rides against skin. Work slowly.
Where you cut depends entirely on your maker, and they genuinely disagree. The Fuzz Factory cuts down the center front and the inner legs. Blue Harbor requires the cuts on the outside of the arms and legs, explicitly not up the inner thigh, and wants the dummy to come off in one continuous piece. Beetlecat cuts down the front.
There is no universal answer, so do not follow a random tutorial's cut line, including this one. Read your maker's sheet, and ask them if it is unclear.
A common sequence is lower legs first, then lower arms, then the torso. Removal usually takes the wearer down to their underwear, so pick helpers accordingly.
Here the makers split again, so this is another section to check against your own sheet.
Re-taping. Eastern Dragon requires the dummy re-seamed along the cut lines with several layers, and charges a fee if it arrives unrepaired. Beetlecat and Kilcodo also want it taped back together with the landmarks matched up. But CityMutt asks for it unrepaired, and Foxes in Boxes says plainly that you do not have to tape it back together.
Stuffing. Most maker sheets do not want you to stuff it at all. That is their job, on their mannequin stand. WildFox asks you to fold the dummy up and put it in a small box, and says it is fine to squish it. Blue Harbor asks for a box no bigger than roughly 12 by 12 by 12 inches.
Drying and packing. Let the shell air out for a day or two before boxing it. Do not seal a damp dummy in a box and mail it across a continent. CityMutt suggests tossing dryer sheets in with it. Blue Harbor asks you not to leave your clothing or socks inside the shell, which happens more than you would think.
Usually, but no longer always. Star Fursuits, Blue Harbor, Foxes in Boxes, Eastern Dragon, Beetlecat, and CityMutt all still require one with no substitute offered.
A small group of makers has moved on. Pseudocanid accepts fullsuit commissions without a DTD, working from a 3D body scan the client exports, on the grounds that scans are easier to obtain and more accurate. Spey Labs does not take duct tape dummies at all and works from 3D scans as part of a digital pipeline. Fursonafy and Koshka Fursuits build to measurements without a DTD.
If scanning appeals to you, that is a maker-selection decision, not a technique you can substitute in. Ask before you commission, not after.
Three to six rolls for most adults. CityMutt's rule of thumb is one large roll per 50 pounds of body weight, which is the only sizing heuristic any maker publishes. Buy one more than you think you need, because running out mid-session with one arm taped is a bad afternoon.
No. You cannot tape your own back, hold a T-pose while taping, or safely cut yourself out. Every maker requires at least one helper, and two makes the session faster and more even.
Never. Tape goes over a disposable coverall, with plastic bags or cling film over the hands and feet and paper towels at the wrists, ankles, and neck. Household duct tape is not designed for skin contact and can tear skin or rip out hair.
Snug at the crotch and underarms, and merely firm everywhere else. If your breathing is restricted or a limb tingles, it is too tight. Cut that section and redo it. Compression is the mistake that produces an undersized suit.
One to three hours of taping, plus a day or two of drying before you box it. Budget an afternoon and do not schedule anything after it.
Ask your maker, but assume yes for a noticeable change. CityMutt advises against reusing a dummy older than about a year for the same reason.
