[avatar user="tonyw" /] These are based on Make a Guitar Pick Box on the Woodworking for Mere Mortals site. I used the hinge design and shape from the Mortal boxes. I moved the base magnet inside the wood (drilled a hole from that back that was eventually covered by the bottom). This way the base magnet isn't visible. That may have been a mistake, they don’t close with as solid a “snap” as I'd like.
I made these for Christmas gifts in 2013. Both of my kids play guitar, so they each got one. A good friend’s daughter, a co-worker's son and my guitar teacher each got one as well. Now that I think of it, I should have made one for myself.
