Step 3 - Using an appropriately shaped file to suit the outline of your pencil mark, neatly file up to the line.
Step 4 - Using 120-grit sandpaper, remove all file marks and round off all the sharp edges, to neaten the coaster's borders.
Step 5 - Once you have the end product looking exactly how you want it, use it as a template to draw out as many coaster shapes as you require.
Step 6 - Repeat steps two to four on all the other coasters, and when they're all sanded, finish off with a couple of coats of paint.
Tip
Use a primer undercoat first, lightly sanding between coats with wet and dry 220 sandpaper for a more finished look.
