Look for handmade rugs with a high knot count. The higher the number, the denser the material, which is better for insulation than a rug with a lower knot count. Affordable machine-made rugs can also take the chill off frigid floors. High-pile rugs typically feel warmer, but if you’re looking for something that’s easy to clean, go with a flat weave. If you have inadequate wall insulation, wall tapestries are an easy decor fix that will help to warm up your rooms. The heavier the material, the better. A quilt will also work. You can even create a fabric feature wall by applying fabric like wallpaper to one or more walls in your space using liquid starch. Unlike traditional wallpaper, the starched fabric is a cinch to remove, so it’s a good project for renters. Thick curtains can work just as well. Wool is an ideal material for curtains, as it’s a highly efficient insulating material. But there are many other options besides wool for store-bought curtains at various price points that are good insulators. Look for packages that are marked with the word thermal or something similar. One room accessory, in particular, can be an unexpected help when it comes to warmth: the ceiling fan. Warm air rises in a space. So if you have a ceiling fan, switch it to the reverse direction from what you normally use for cooling the room. This will push the warm air back down toward you, making the whole room feel toastier.
