This 17" throw pillow cover features a beautifully embroidered Pi symbol cleverly composed from its digits; to best continue the pi theme, I chose a cotton print of scattered rings in rich chocolatey browns. There's a zipper closure across the bottom edge to make it easy to remove your pillow form for laundering. I suggest an 18-20" insert to fill this cover to a nice level of plumpness.
Pi Rings pillow cover
Please note that pillow covers are shipped WITHOUT a pillow form for two reasons: it saves on shipping costs, and it allows you to choose an insert that best fits your firmness preferences, filling choices, allergen considerations, etc.
