I always like to organize sticks and mallets so it's easy to keep matched pairs together. One easy way to do this is to use a permanent marker and draw a line or pattern around the stick. Make sure each pair has the same pattern in the same part of the stick. You can vary the color, spacing, or placement of the line so it's easy to find a matching pair. You can also use tape, but remember that this will affect the weight and feel of the stick or mallet.
A couple years ago my colleague and I were looking for the easiest way to organize reeds for those moments right before rehearsal or a concert when a student suddenly needs one. It turns out the best solution was under $20 at Home Depot.
