FAIRFIELD Crafter’s Choice® inserts are designed for everyday throw covers, DIY décor, and needlework pillows that need a supportive form. This 16 x 16 in (40.6 x 40.6 cm) size is a flexible standard for sofas, beds, and reading nooks, working well with a wide range of cover fabrics. Adjust the fill through the zipper if desired, then spot clean and let the insert dry completely before returning it to a cover.
