Getting Started: Blockplate 12
Peel your letter locator template guide from it's backing and stick it on your Blockplate.
Position the template as so the letters fall inside each box.
With a marker, place a dot in each box for the first 4 letters of each word in your seed phrase (for 3 letter words, leave the last space blank/empty). Why only the first 4 letters?
Double check each letter and word.
Using an automatic center punch, punch down at each marking.
This will make a physical and permanent indentation that will show up within each box.
Peel the template off to reveal your seed phrase physically (and permanently) marked on steel.
Securely discard your used template. Repeat on the backside with your remaining words.
