CWD prefers overstuffed down inserts for all her pillows & projects. To achieve an overstuffed look- we recommend buying pillows an inch bigger than the pillow cover. Down inserts can be found at retailers such as Pottery Barn, Crate & Barrel, West Elm and online. Please be careful when inserting overstuffed down fills as to not cause stress on the zipper and possibly pop the pillow seam. Alternatively, inexpensive polyester fills can be used as well.
