I make my own sanding sticks: I buy packages of wood or craft sticks in several sizes from a craft store and apply double-sided foam tape to them, cutting with a hobby knife. Next, I peel off the backing and apply the tape to a piece of wet-or-dry sandpaper of the grit I need, then cut the paper using the stick as a straightedge. I like to use
600-, 1,000-, and 1,500-grit sandpaper.

To use the sanding stick, I dab my finger in water, drop a little on the plastic model, and begin sanding.
