Oh, boy! Good information and happy to know about these issues. I keep an ongoing journal of the quilts that I make. A photo, the name, who it was made for, the fabric top and back, the batting and the date completed. From this post, I am going to be much more specific from now on and journal the thread color, type, top and bottom. And now, the fabrics that I used, the maker and the date purchased. This is just for me so the more information, the better.
Right now I am making, what I call, a floating log cabin quilt, which has a great deal of white fabric. The white fabric is Kona and I am so disappointed in it because it is fraying quite badly. The fabric was laundered and starched before cutting. As I was piecing the blocks and noticed the excessive fraying, I starched the back of the block hoping this would help it hasn't. The problem with using the white fabric is that you are able to see through it and every thread shows in the front. Quilting helps disguise it and so I am hoping that the quilting I do will hide the threads.
