Picture of Teenage Mutant Ninja Turtles
Last year I completed my personal favorite turtle, Mikey.  It took me 1 year to complete the costume, but there couldn't be just one turtle.  SO, it was a must that I complete his three counterparts.  After 2 years from the birth of the idea to create the ninja turtles, they are finally finished and ready to clean up the streets!

Step 1: Research

First thing I did was to buy the TMNT dvd set.  I watched all the movies to refresh my childhood memories of the amazing films.   All the movies are amazing but I had to go with the first movie's costumes.  The nostalgic value and just awesomeness of the original costumes can't be beat.

I did some research and figured the best approach would be to sculpt the entire costume.   Even though I had no experience at sculpting, I wanted something challenging.  My first sculpts were laughable. But with the encouraging help from members at the Replica Prop Forum, I was able to hone in on my sculpting and the improvements speak for themselves.

I would LOVE to have one of these costumes. How much would you charge to make one, as I have neither the skill nor time for something like this. I'm 5'8" BTW in case that makes things a little easier with existing molds.

Since you have all the molds already done, would you ever make one to sell? And if so, how much? Great work!

Awesome costumes! This is actually my goal. Crazy question, but how did you see out of the costumes? It just doesn't look like you'd have much vision there.

Thanks everyone! The goal was to replicate the original movie from the 90's.
To answer the question...
Cost: didn't keep track and don't want to remind myself but in the thousands I'm sure. Don't let the cost be a discouragement though. There are cheaper materials that can be used and a smaller project cuts the cost tremendously.

Beebop and Rock Steady: who knows... I'm currently trying to decide my costume/s for next year and I'm not counting them out!

Out of control amazing and impressive. Congrats on the outcome!
You should try to make the '80s cartoon I think that would be pretty awesome
They look more like the costumes from the final movie.
I am probably the biggest ninja turtles fan great job! One question though how much does this all cost ( tools included?)
