Hello, I'm from Germany and we too sew such bags and give them to patients who need drainage. First we sewed "Heart Pillows" for women who suffered from breast cancer to ease their pain under the arm and gave these to the hospitals where the patients recieve them after surgery. And then we were asked if we could sew such little bags!! Over here there are many groups sewing heart pillows and such little bags and all is given for free to the patients!!
