This Homemade Female Halo Costume is a female version of Halo that my hubby made. It was made from pepakura software that you can download and there are many many files of what costume you want to make. The software will print out what you need, then you just cut out and glue them into shapes. Once that is done, you can use fiber glass resin to coat the parts so they are strong and rigid. Youtube will have tutorials on how to apply them plus bondo if you desire. After the fiber glass resin is dry you then paint and detail.
It is inexpensive but very time consuming project. Well worth it in the end though. Any questions feel free to contact me.
