This is a top that I made for myself. While writing the pattern, I determined it would be great for nana during the cold months. She could simply turn the sleeve so that there is access to her fistula.
Pattern is available on Ravelry and craftsy and is named Dialysis Sleeve Top on both sites.
This top is also available to other dialysis patients that are interested. It is made to order, your choice of size (small, medium, large, or extra large), and your choice of color.
