Step 6

Cut the fabric into a piece 45” wide by 3 yards long. Fold sides and ends over of outdoor fabric, and sew to hem edges of sail. Fold corners in and stitch to allow a channel for rope to thread through. Screw I-Bolts into corners of deck boards. Tie rope between I-bolts and sail, pulling sail over dowel and tightening down.

Finishing

Sand all surfaces, starting with a medium grit and finishing with fine. Wipe off the dust, fill any holes or gaps with wood filler, and sand smooth once dry. Apply primer if you're painting, then finish with your choice of paint or stain and seal with a durable clear topcoat. For outdoor projects, use exterior-rated primer, paint or stain, and sealer so the piece stands up to the weather.
