Recently I modeled a Saber Extra cosplay costume for the company FineHorse. FineHorse specializes in high end cosplay costumes, props, and accessories. They've recently started selling to the US market after catering largely to Europe and Japan for a decade. There aren't a lot of resources detailing the quality of their work in English yet, so I hope you will find my photos and notes about the costume's construction helpful!
I have a supply list of products I have used or otherwise recommend.
They are compiled on this Amazon Page.
Many of my Tutorials include links to products I use that are part of the Amazon Affiliate program. Using these to make your purchase provides me with store credit that covers new supplies for this blog's projects!
