Lovingly stitched by a grandmother in Wisconsin, you put this pillow in the microwave for 3- 5 minutes. The heat emanates from the corn and is soothing for aches and pains. It holds heat a long time and has the softest flannel pillow case. You slip the pillow in or out so you can launder the case. Her phone # was on the pillow ticking and that is how people know about her. I was fortunate my friend lent me her pillow for healing purposes since the “being rear-ended last Friday accident.” I hear they are great to take to bed everyday, especially in the winter. Every once in awhile if you use the pillow a lot, you need to return moisture to the corn inside- pop the pillow in the freezer for a day. Then heat again. Not sure the official name of these handcrafted pillows but they are wonderful. R-E-L-I-E-F. I called her today and ordered three. Fifteen bucks each plus shipping. Worth it!
