Hmmm.... I wonder if you asked in a "McDonald's Big Mac Sauce & Sauce Creation methods" board? If you did, I would hope you'd receive some sort of useful response, based upon the title of the board.
Take a closer look at our board title... "Spidey Suits & Suit Creation methods". From the title, I'd expect any question about Spidey suits and their creation to be fair game. If you choose to not answer that is your business, but to ridicule someone for asking a question appropriate for this board is uncalled for. This board is for exactly that kind of question. "How did you do that?" is a great Suit Creation method question.
On the other hand, if someone wants to use this board as a "show off" opportunity, there's nothing wrong with that either! "Spidey Suits" is the first half of the name, so show off!
For those who have worked very hard and put tons of time into developing an awesome suit creation method, I can understand that you might not want to give away your secrets. Maybe you'd consider putting together a general "how to" file or even a DVD and sell it to interested people? You don't have to give away the secrets, just show how to put the pieces together, etc.
You've got a great point there about the "show off" thing. When I first came here I felt the same way...still do somewhat.
What you've asked is a huge question...but here goes:
1. First you have to decide which kind of suit you want - comic-style or movie or a variation
2. There are two basic ways to make a spiderman suit - either get a pattern dye sublimated (printed) onto 4-way stretch spandex or have normal red and blue cloth cut into patterns
3. If you go the dye sub route...you're going to need a pattern. There's a pattern floating around...and it's also on some SpideyDIY site. That pattern is the "SpideyBoone" pattern. I've been told that this pattern has the dimensions and proportions of the arms and other parts slightly off. I've also heard that the dimensions are NOT off. So you can try that method if you want.
*****Theoretical idea...might not work...just theorizing****
If you are REALLY industrious and want to start from scratch, what I'd do is make a duct-tape dummy (google it) from head to toe then sharpie your proposed seams onto the tape..then cut it all out...then scan it piece by piece. Once you get there...at least you have a base pattern.
You could go further and find a muscle pattern and try to scale it correctly. But that'd be tricky because the way most spidersuits are shaded doesnt look like the pictures online.
Then you'd have to, piece by piece, figure out how to draw the weblines.
Now, if you're content with just drawing the lines, you might use 3d Tulip fabric paint. You could also use a Sharpie (yes people do that).
If you want 3d lines, you could cast 4mm thick lines of urethane tinted back (SpiderMilk did a diagram) and glue those down in the correct spots.
Or you could do a clay sculpt...cast that in plaster or silicone...then pour black-tinted urethane in...then glue it down.
Find good picture of some spiderman eyes you like ...sculpt them in clay, mold them in plaster/silicone and pour in urethane.
The lenses? there's a mesh method...and a white cloth method.
4. If you go the route with 2 different fabrics, you'll want to try it out with newspaper or muslin to make the pattern off of your duct tape dummy. Then look above and figure out how you want to do the webs...like I said above.
If this sounds like a complete mess to you...well it's just a glimpse of how hard it is to do this from scratch. But it's not impossible...someone started from scratch before
BTW...here's the comic spidey me and 2 friends have created...and are selling for $399 + 20 shipping.
We also have a Movie version with 2d printed webs...
Also 399$ + 20 shipping.
