    These step-by-step directions are designed to save you the expense of new pillows. The envelope design of these pillow covers makes them removable slipcovers for your throw pillows. Always preshrink your fabric so that your finished pillow covers stay the same size after washing.

    Materials needed

    Note: The cutting directions do not add a seam allowance so that the finished pillow cover is a little smaller than the form and creates a "plump" pillow with no empty space.
