Step 2: Make Your Shark Patterns

I worked out the size and shape of the shark using paper patterns. I've included the shape I used below so you don't need to work out the construction but I'd still recommend making a simple, small paper pattern to judge scale against a doll and then scaling up the measurements from the height of the doll to your own height. All the shapes needed to cut the various foam pieces are included in the 4 downloadable SVG files. Download each pattern and change the file suffix from ".tmp" to ".svg" when you save them to disk. Open them with your web browser to see the patterns if you don't have a vector application.

A major factor in the size of the shark relative to your body is that it has to have a large enough mouth to wrap around you without the body looking too short and stumpy. It will probably have to reach right up to your chest rather than sensibly around your waist - this costume is about fun and effect, not comfort and convenience!

The shark's grey back is made from two identical halves, one paper pattern will reverse to make both. To save foam (I didn't know exactly how I was going to do everything at the time) I cut the tail out separately but you could include it in the body pattern.

It turns out I'm about 6.35 times taller than a 1970s GI Joe doll so once I had a correctly-proportioned copy paper shark I simply took it to pieces and scaled them up 6.35 times on to huge sheets of paper.

Although the first couple of paper sharks were drawn freehand, once I was satisfied with the shape and size relative to the doll I flattened out the pieces and scanned them into my computer. I then traced out a neat version in Adobe Illustrator - I've attached it as a SVG file for anyone that can use scalable vector files. I scaled it up in Illustrator and drew it fullsize using a large plotter. If you don't have a vector application then open the file in your web browser - you could print it at A4 or US Letter and then scale it up, either drawn by hand using a grid or maybe something like an overhead projector. It's a simple shape so you could simply draw it fullsize by eye. The gentle curve along the top of the back (where the dorsal fin will go) is the most important bit as this gives the 3-D shape to the shark's body when the halves are glued together.

Repeat the drawing process for the two pectoral fins and the dorsal fin. You could include the tail at this point but I haven't included a plan for that as I measured up and drew it by hand once the main body of the shark was glue together so I could get the shape and size I wanted. If you have a big enough sheet of foam you could simply include the tail as part of the main body halves but I had to place it on the foam separately.

Finally, draw out the pattern for the u-shaped 'muzzle' area.
<p>I'm looking to do this for a school engineering project. So I need to get some of this &quot;zotefoam.&quot; I have found pretty much the same material here in the US, but I need to know how much to order. Do you have a rough measure on the square meters of the &quot;zotefoam&quot; need to build the costume?</p>
Hi, it's a long time ago now but all of those various forms of foams come in standard sheet sizes. I think they were mostly six feet by four feet or maybe eight feet by four feet so a single sheet would be plenty. Probably two metres by one metre metric. Remember the stiffer, more plasticky Zotefoam is only for the white bit, (the belly and offcuts for teeth). I think it's a polyethylene foam or something like that. If you look at the downloadable files there is a very simple pattern for the belly sheet. Print that out, look how far up my body my costume comes and then measure yourself to see how far up you want the shark to reach on yourself. Then scale that pattern up to the height you want (you don't need to print it full size yet, just take scale measurements off the pattern and it will give you the width for the height). The main grey back and fins of the shark were made from normal upholstery foam rubber. You'd take the scale for those bits from the scale you worked out for the belly piece. Hope this makes sense - look at the belly pattern and you'll see how simple this is.
<p>Forgot to suggest that you search the web for cosplay armour build sites, nowadays loads of people use foam for costume building and list their suppliers on cosplay forums. It's much easier to find now because of these resources.</p>
<p>with just a few days left to Halloween, of course I waited till the very end, how can I rent this Shark costume from you. </p><p>Danhoenig@gmail.com</p>
Where are you from? I live in the UK so if you're in the US I'm afraid it'd be prohibitively expensive to start sending sharks across the Atlantic!
Hi, and thank you for getting back to me.<br>I am in Miami Beach, Fla.<br>Just wondering what Fed Ex would charge to get it there by Friday. I know it's not heavy, just bulky.<br>Thank you again.<br>Danny
always funny when u get an email with someone in your local nightclub lol spiders is so easy to recognise anywhere lol
SNL stuff is pretty much unknown here in the UK but I was introduced to classic SNL back in the 80s. The Landshark was one of my all time favourites and my GF very kindly bought me a Landshark t-shirt ( off the internet and despite not really having a clue what I was talking about! ) this Christmas :)
I haven't paid attention to the instructions, i only looked at your fabulous costume. wondering, can you walk when you are wearing it?
Lol, not really! If you read the instructions you'll find the bit where I mention the awkward penguin waddle. I did have to walk a few hundred yards and then queue to get in to the nightclub and then I was wandering around for hours in there so it's perfectly doable, just ungainly. On the whole I found it added to the effect as I rocked and shuffled through the crowd it seemed to attract attention and laughter. Stairs are very tricky though as leg movement forwards/upwards is fairly limited by the flexibility of the foam rubber. It was only four or five steps up into the club and that was plenty...
now all you have to do is wear an old flannel shirt and hat, and hire out a large fishing boat!<br><br>(500 points for the reference!)
Love it!!
Ah, OK, I'm lost on this one. Was a childhood Batman fan, not so much in to shark films, lol. I'm sure something like that happens in one of the assorted Jaws films but the hat just made me think of the Old Man and the Sea although I think he had a small boat and the sharks only ate his Marlin.
Quint from <em>Jaws!</em><br> <br> -500 points!
Oh well, it is more than 20 years since I last saw Jaws and for some reason I was thinking of a wide-brimmed sun hat, never thought of the peaked cap.
True, true...<br><br>by the way, nice costume!
LOL! Ingenious. Well done!!!
Ta for the support!
Hand me down the shark repellant bat spray!
Awesome, my very first instructable and possibly the best comment I've ever seen on here, thanks! I'd forgotten all about that so now I'm off to Google to see if I can find a still of that scene to bring back childhood memories. A great moment in cinema history.
Found it... all copyrights credited to original owners, creators, etc, nowt to do with me :)
hahahaha I wasn't expecting you'd know about it. Next year dress up like batman and have the shark on !
What a great idea! I think most of us had tought in some custome like a monster or a beast eating us in some time of our lives. But your costume has fullfilled my expectations so far!
