Let's face it, no one really knows how Peter completely made such awesomely complex looking costumes in either Spider-man 1 or Amazing. It's like, let's get started with some designs (Amazing adds a bit with the eye pieces), and then later "screw-it" he's Spider-man now.
Wait. Of course we know how he did in TAS. They show him searching the web for spandex. We can pretty much conclude that he ended up buying spandex from some online store and embossed the spider ensignia on it.
