First, let's talk about the clothesline we need. I used cotton clothesline made by SecureLine that is 3/16 inch wide. I bought this at Wal-Mart. The person who I learned this method from said that it’s important to use cotton clothesline and not the nylon or synthetics. This 100 foot package was more than enough to make that first bowl shown above. I used about 3/4 of the package (75 feet) on it. The second bowl was larger so I used up all of a package plus the remainder of that first package, so about 125 feet.
