Instead of settling for a print that's not quite right, make your own outdoor chaise cushions using inexpensive pillows and the fabric of your choice.
For each cushion, you'll need four polyester-filled bed pillows and waterproof fabric meant for outdoor use. We used 22-by-18-inch pillows and a 46-by-77-inch length of fabric.
Fold fabric lengthwise, right sides facing, and sew the two short ends shut, leaving a 1/2-inch seam allowance. Turn fabric right side out.
Using a water-soluble pen and a ruler, mark horizontal lines to divide fabric into four equal parts; pin, and sew.
Sew two pairs of 12-inch lengths of twill tape to each opening. Insert pillows, and tie shut.
The fabric will protect the pillows from moisture, but it's best to take the cushions inside before it rains.
