As a beginner guitar player, I'm very annoyed that my picks just disappeared every time I paused strumming for a few moments.
Step 1: What I Used
It's a short list of things I needed, to make my pick magnetic:
-a small rare earth magnet (I got it from rolling paper packet, but you can buy them online or some craft stores.)
-a drill bit with the same diameter as your magnet
-a cordless drill
Step 2: Measuring
There's not much to say. It's 5mm in my case.
Step 3: Drill the Hole
Drill the hole somewhere in the middle of the upper half of the pick.
Be careful if you use a very thin pick not to break them.
I used a piece of scrap under the pick to support it.
Step 4: Fit It In
Just push the magnet in. In my case it was a very snug fit, so I think it would have been good to go.
If it's too snug, or you don't get it in, you can use some sandpaper to make the hole a bit bigger.
Step 5: Secure With Some Glue
As I said, I think the snug fit would hold it, but I wanted to be sure, so I applied some superglue and set it to dry.
Step 6: Get Started
Well, it's finished. Start playing, and if you stop, just put it on your E string, or a screw, or wherever it will stick to your guitar, or bass, or ukulele, or whatever.
