The first step to creating your own memory foam pillow is to find a pillow stuffing that is similar in size and shape to the one you want to replace. Grab an old pillow, lay it flat and try to cover its entire surface with the stuffing you want to use. If the pillow is a standard pillow, use a standard filling (I used shredded memory foam). If your pillow is a down pillow, use a feather or synthetic filling. If you have an ironing board and pillow case, you can use that too.
