I don’t crochet or knit but I had to share this. My mother’s friend has been recently diagnosed with breast cancer after 10 years of remission. My church has a prayer shawl ministry where the chicks with sticks parishioners make hand-crafted afghans and shawls while saying prayers for the sick. I received a shawl back in my chemo days and found it very comforting. The shawl pictured below was given by my mother to her coworker. The fiber that was used was very soft and lightweight.
One thing I personally found to be very helpful after the surgeries was a mastectomy pillow. This is just a small pillow that the patient puts between her arm and her torso. It does make the patient feel much better. Apparently cardiac patients also find this to be helpful in removing the achiness.
