Make sure that you collect and save all of the inner pieces after cutting to use for assembly.
Step 3: Assemble
Once you have the pieces cut, remove the backing on the cork, and place the outer section of one color acrylic on it. Now use the inner sections of the opposite acrylic to fill in the spaces. The adhesive side of the cork will hold everything in place.
- Use the pieces left over to create a second coaster.
- Make the graphic larger, and cut it out of thicker wood to create a trivet. Discard the inner pieces and put small rubber feet on the bottom to protect your table.
- You can also use felt to line the bottom of the coaster, just make sure to use adhesive on the outer and inner pieces to secure everything in place.
