Use an acrylic cutter to cut two .093-inch-thick acrylic sheets to desired size. When using the acrylic cutter, align it with a ruler or T square to ensure a straight line. Once you've scored the acrylic sheets, snap the sheet against the edge of a table. We made our sheets 16x20 inches, but you can customize the dimensions to fit your existing artwork. If you opt for a thicker acrylic sheet, the cutting tool might not work. However, many home improvement and hardware stores will cut acrylic sheets to your desired size, which can save you time and effort.
