This is the PATTERN for the Dialysis Fistula/Graft Cover Sleeve. This was made with my grandmother in mind. She has an AV fistula that is currently being used, and a graft that clotted off and is unable to be used. She does not like looking down at her arm and seeing the failed graft. This cover pattern comes in 3 sizes; Small, Medium, and Large. I DO NOT recommend trying to recreate this without a pattern, unless you or someone close to you can test the product. If it is made and too tight, this will cause the fistula/graft to fail. Dialysis patients can not have tight fitting sleeves because it will cut off the circulation to the fistula/graft. If you have any questions or concerns about this pattern, please contact me and I will get back with you as soon as possible.
