ok now your in trouble....starting from scratch. good place to start actually IMHO.
I'll use my first suit as an example, if the all the components are seperate arms, torso, legs...etc etc.
there are 2 ways to go about it
1st you can attach all the components to a undersuit with rubber cement and rubber latex for the seams
the pros of doing this is the hard work of sewing a suit together is all ready done for you. All you need to do is fit and glue the right pieces on the undersuit and then using the latex to make the suit appear seamless.
the only thing i have against this proccess is you can't really"feel" the suit on you. hard to describe
2nd proccess is to actually sew the suit together arms to torso legs to torso...you get the idea.
This proccess requires patience.
Once all the pieces are sewn together you can then take rubber latex and apply it over the sewn areas to secure the Stitches and again seam the suit together.
the only thing i have against this procces is the amount of time it takes to do it.
when i started building my suit, I tried both methods and I would say for me the best method was the 2nd. Find out what works best for you..
I hope it helps
here is an example of method # 2
