X marks the spots! It's friendly-looking, despite being built from things usually used as cautionary symbols. This is a property which I also perceive in many of the sprites and setpieces of the "Metal Slug" video game. Hmm... maybe I should Fontstruct some actual Metal Slug fonts!
This works as a pixel font, but only at 2x the original size or more because of the close spacing. Smaller sizes will create distortion unless you modify the spacing in-software.
So this is basically how you can design each letter of the alphabet using 2x4 wooden planks. I can also show you the difficulty level for some of these letters. For example: the letters L, T, and I are the easiest to make, letters like R (which is what I'm gonna make) is in the medium level, and the letter G is the hardest to make. Examples of letters that have similar difficulty levels include Q and O (where Q is just an O with an extra thing at the bottom), E and F (where E is just an F with an extra 45° angle at the bottom), and W and M (exactly the same difficulty, with W just being an M upside-down). But, even though G and C have similar shapes, the letter G having an extra line makes it indeed much harder to make than the letter C, making it actually the hardest to make out of all the letters.
