I go for simplicity.. one reason that I love samplers. I almost always have a block..or a few that are cut out and have small copies of piecing diagrams for that block. I put a piecing diagram, the cut out, marked pieces for said block, a small pair of thread snipping scissors, a spool of thread with needles threaded on it, and a little pin packet, made of a small piece of quilted fabric to store a few sewing pins in. You could also add a thimble if you use on.. I put it all in a zip lock bag and drop it in my purse.. depending on where I'm going I'll tuck one or two (or more) in and enjoy while I'm having "downtime" wherever.. I've done that for years.
