Place the mask over the top of the coffin lid (you may find it easier to tape it down so it doesn't move). Tap the versamark all over the mask, making sure the lid is fully covered in the pattern.
Remove the mask and cover the pattern in clear embossing powder. Set it with the heat tool.
Fold and burnish all the scorelines on the box and lid.
Assemble the box and lid. I used liquid glue, but you may prefer to use tear and tape.
Fill with treats. I bought bubbles, jelly body parts and chocolate eye balls from the pound shop.
Punch out the label in some black cardstock and emboss Happy Halloween in silver embossing powder. Pierce a hole through the label and tie on some silver metallic thread. Tie the ribbon round the box and attach the label to the ribbon.
