Alright, let me tell you about something that got stuck in my head the other day. I was just fiddling with an old baseball I keep on my desk, you know, the kind you toss up in the air when you’re thinking. And it hit me – how many seams are actually on this thing?

My first guess, like probably most folks, was two. Makes sense, right? You look at it, you see two pieces of leather shaped like figure eights, or kinda like peanut shells, stitched together. So, naturally, you think, okay, two pieces, two seams where they join up.
So, I decided to get practical. I put my finger right there on a stitch, on what looked like the start of a seam. And I started tracing it around the ball. Following that red thread, nice and slow. It went around one curve, then crossed over itself, went around the other side… and kept going. And going. And here’s the kicker – I ended up right back where I started.
I tried it again, thinking maybe I messed up, lost my place. Nope. Same result. That seam just looped and looped until it met its own beginning. It wasn’t two separate lines meeting somewhere; it was one single, continuous path snaking all over the ball.
Wait, Just One?
That felt weird. Could it really be just one single seam holding the whole thing together? It seemed too simple, almost like a trick question. The way it crosses over itself really throws you off, makes it look like multiple seams intersecting.
After turning the ball over in my hands for probably way too long, feeling a bit silly, I did what we all do eventually. I kinda vaguely searched online. Didn’t dive deep, just a quick check like ‘baseball how many seams’.

And there it was. Plain as day. One continuous seam. Turns out those two pieces of leather are stitched together with one long thread, making one single seam line. The whole thing is just one big loop, cleverly designed to cover the sphere.
Funny thing is, knowing it’s just one seam doesn’t make it look any less complicated when you stare at it. All those stitches, someone told me there are usually 108 double stitches, holding that single seam together. It’s pretty neat, actually. Just goes to show, sometimes the simplest questions about everyday things have answers that make you stop and think for a minute. Anyway, that was my little adventure in baseball anatomy for the day.
