I have an erratic heartbeat and as such need to keep it calm, as it goes off the scale quite a lot and makes me feel ill etc. I found that making this large circular blanket helped me keep my heartbeat level, and lower and stop the racing. I have made 4 large blankets so far and have found that I this relaxation is enabling me to take less medication (agreed by my doctor). This blanket I gave to my mother-in-law as she was moving into a nursing home, and I thought something so personal would help her settle in. 6 months after giving her it, she still talks to all the residents about it and is very proud that her son-in-law made it for her.
