Here's the link to the pattern!
I used the beanie pattern on the top, which I found to be simple and easy to follow if you're used to working with double pointed needles. The only complaint I have is that the pattern does not provide a gauge swatch. I made an entire hat on size 4 needles, as recomended, and came out with something fit for a retro-inspired toddler. That said, I switched to size 8 needles, still using regular acrylic, I Love This Yarn brand yarn, and the hats came out perfectly man-sized and comfy. It took less than one skein, but I would recommend buying two so you can make a matching scarf! The I Love This Yarn brand is great for guy-knits because it's super soft without being visually and texturally overwhelming.
To make a scarf that will go with these hats, I figured I would use ribbing as a tie-in, but also to make them thicker and warmer. This pattern is super simple, and great for a generic "guy scarf"- not too stylized, but without the shabby or rustic look that some simple knits can end up with.

Continue until you have 60 inches or so. You might have the recipient try it on so you can make sure it's long enough to not look silly, especially if it's for a taller guy.
Wasn't that simple? :)
