If all the ductwork must be replaced or added inside intact walls, it can cost $2,700-$12,000 or more to install gas central heating with a standard-efficiency gas furnace and $3,500-$22,000 or more with a high-efficiency unit.
I want to make a different-sized blanket! How much wool do I need? In my experience, you get about 600 square inches per pound of wool. Why do I have to felt the wool? I thought superwash wool doesnât felt!
To make a single layer fleece blanket, you use the same method, except that there's only one layer of fringe involved. I usually make the fringe for single layer blankets about 2 inches deep and 1 inch wide. You can also see my tutorial for them here.
