Cut fabric 2 1/2" x WOF. Fold the left side to the center of the wrong side of fabric, then do the same for the right hand side. Place the clothesline on the center covering where the 2 sides come together and fold both sides over the clothesline then stitch. You can either stitch through the clothesline or just to the side of it. (I hope it's clear. Or, use a pattern by Auntie's Two....she has lots of techniques for covering clothesline.) I used to do clothesline a lot but am now in love with the scrap batting technique that ends up looking like you covered clothesline and is much faster and cheaper because you use scrap batting (and we all have that)!
