Draw a circle with your pencil on the plywood sheet. The circle can be as large or small as you want, depending on how much of a focal point you want the crown to be. For easier cutting, draw it as close to the edge of the plywood board as possible. Within the circle, draw a second circle that’s approximately 2 inches smaller than the first.
Put on safety goggles. Cut out the exterior circle using a jigsaw. Move the saw slowly so you’re able to stay as close to the outline of the circle as possible. Find the center point of the circle and cut it in half (you’ll now have two equally sized semicircles). Cut out the interior circle on both halves. Keep the outer circle only; the interior circle can be discarded.
Measure and cut five strips from the plywood. Use the tape measure to measure the strips, which should be 2 inches wide (same as the circular cutout) with the length determined by how tall you want the bed crown to be.
Set one of the semicircles flat in front of you with the ends facing you and the curve pointing away. Apply wood glue to the ends of the strips and place them upright on the semi-circle (one at each end, one at the top of the circle and the remaining two halfway between). Allow the glue to dry and then add more glue to the tops of the strips and place the other semicircle on top. After the structure is dry, use your hammer to nail the components together for added stability.
Cover the exterior of the frame with fabric. Stand the frame on its "feet" and drape the fabric over the top. In order to hide the frame, use either a thick or opaque fabric. Cut it to size with scissors and fold it around the frame. Turn the frame upside down (resting on the curved part) and use a staple gun to attach it to the inner side of each semicircle.
Staple the ends of the fabric being used as the canopy to the bed crown. This fabric doesn't have to be the same as the one used to cover the crown, but it needs to be long enough so that it stretches all the way to the ground. Staple the canopy fabric to the inward-facing side of the bottom part of the frame.
Screw an L-bracket to the end support (feet) on each side of the frame, using your drill and screwdriver bit. The other arm of the bracket is used to attach the bed crown to the ceiling. The bed crown can also be attached directly to the wall by drilling through the end supports, but because of the shape of the bed crown, this may prove more challenging.
