I've been looking around to get some pointers on how other people are building their costumes, and I have to say your posts are very helpful. Not only are you awesome at what you're doing, you may just be the coolest dad on the planet!
I'm in the process of gathering materials for a Scarlet Spider build (Ben Reilly--Not the Kaine version) to surprise my son, and I think you may have just inspired me to make him a Mile Morales suit once I'm finished. I would love it if you could give me a more detailed explanation of how you fit your mask pieces together. My son (he'll be four soon) has all kinds of Spidey costumes, but the masks are terrible. They fit horribly, so he's constantly struggling to adjust it as we play. Any advice or detailed instructions on the mask would be greatly appreciated. Great work!
