Materials needed:
Corrugated cardboard: Boxes, packaging, etc.
Stanley / craft knife / scalpel or scissors
Tape
Ruler or, in my case, a plank of wood. Anything you can use to cut a straight line.
Using a plank of wood as a ruler I used a Stanley knife to cut strips of cardboard, making sure they were of similar widths by cutting them the width of the plank. If using a ruler you can measure the widths, but that's a lot of effort for something which doesn't require such technical control. Cut across the corrugation, not along it, so you see the zig-zag of cardboard filler within the cut.
Roll a strip of cardboard up tight: see photo above. Pull the strips through your thumb and forefinger to soften them and make them easier to roll up tight. Secure the end of each strip with tape, attach the next strip and continue. Eventually you will have made something that looks like this.
I was so absorbed in the project that I forgot to photograph the last step: making a base for the tray. A base is necessary if you intend to scatter some catnip into the tray.

Place your scratching tray on a piece of cardboard which is of larger diameter than the base of the tray. A few inches is plenty. Draw around the tray, then draw a larger circle around that, making a border a few inches wide. Cut a series of slits into the border, to create tabs.
Replace your tray into the circle and bend the tabs to touch the sides of the tray. Wind some tape around the tabs to secure the base. Cover with another strip of cardboard to hide the construction. For illustration I've reproduced and photographed the technique below. Picture the orange Post-it as the piece of cardboard. C'mon guys, use your imagination here!
Add catnip and cherish your unscratched furniture!
