Wanna make a kippah for my rabbi, what should I embroider on it?

I can sew and embroider (both by machine and by hand), and I wanna use these skills to make a gift for my rabbi (maybe for his birthday, maybe I’ll give it to him before then), inspired by someone on either this subreddit or the r/jewish subreddit (I forget which, sorry). I wanna make it personal, but I’m having trouble deciding on a design to embroider on.

He’s a guitarist, huge Steely Dan fan, loves his kids, has a good sense of humor, and is a wonderful advocate against hatred, not just towards jews but towards muslims, lgbt, and other communities as well.

I’m thinking either the Steely Dan logo or something to do with guitar, a silly Jewish pun (like “shofar so good” or “happy challah days”), or some quote that reflects his values. I’m probably overthinking it but I would really appreciate some help deciding!
