As a NICU RN for over 20 years, I have worked in several different units and used a variety of covers on isolettes. Most of them were donated by different volunteer groups. Some worked better than others. In an effort to provide my current unit with some consistently well-made covers that are developmentally appropriate (blocking noise and light) and durable enough to stand up to the rigorous laundry process we put our linens through, I came up with a design that uses recycled scrubs backed with fleece. A pdf of the instructions is available here: Isolette Covers All proceeds from the sale are used to purchase supplies to keep making the covers for our 65-bed NICU. Thanks for your support and happy stitching.
