You need to pick a piece of material which is bigger than 270 × 400 mm in order for the piece to be able to be cut from it. The piece I chose for this project was 1/2 inch thick.
Set your piece up, open the easel file and let it carve.
Sand all the pieces and apply your finish of choice. In this case I went for some Danish Oil, for a beautiful and easy finish.
Once the parts of the project are carved, grab a strip of any kind of fabric and glue it across the bottom side of all the pieces, making it the support that will hold the piece together.
