Got a beautiful kilim or other fabric pillow cover but need the stuff to fill it? This handmade insert is exactly what you need. It's essentially the 'inner' part of the pillow – a simple cotton fabric bag pre-filled with fluffy, hypoallergenic polyester fiber. That means it's soft, holds its shape well, and is safe for most people with allergies. They offer a huge range of sizes, like 10x20 inches (a common lumbar size), 12x24, 16x16, and even bigger ones like 16x48 inches. Just pick the size that matches your empty pillow cover. The quality is great for the price, and it really makes your finished decorative pillow look plump and professional. If you need a weird custom size, you can even contact them to ask about it. A must-have for anyone who loves to switch up their home decor with different covers.
