The EVA Foam
Field Guide
Every foam failure is a decision. These are the decisions.
Most failed builds fail before the first cut — wrong foam, wrong thickness, wrong surface. This is the reference that makes those decisions for you, built to live at your bench.

What's in it
The failure map Four failures, traced back to the decision that caused each one.
The Shore C decoder What the number means, what to buy, and why "Shore 60" alone tells you nothing.
The thickness chart 2mm to 10mm, matched to the job, drawn to true scale.
The buying guide How to read a foam listing, and the five red flags that mean walk away.
I'm Ren. I run Vaelrys.
Years ago I built a sword, followed every step, and couldn't look at the thing when I finished it. The seam ran up the blade like a scar and the whole thing flexed like a pool noodle. I decided I wasn't good at this, and I quit for a long time.
I wasn't bad at it. I'd bought the wrong foam. Nobody had told me there was a right one.
This guide is the thing I needed then. It's free because this hobby's problem isn't talent — it's bad information, and I'm not going to charge anyone to fix a problem the market created.
You did the steps. The steps were fine.
Nobody taught you the decisions.
