I would have asked her if she was writing a book.
Last week I went to my favorite fabric haunt. There were about five other people there when I arrived. I talk to fabric so naturally two of the others and I started a conversation and quickly became enablers of one another. When these impromptu encounters ask "What are you going to make?" Usually the response is "I haven't the slightest idea, I just know I want it." It always ends in an exchange of ideas and other pertinent information. We are definitely not Fabric Snobs. We share fabric, ideas, patterns, and assistance choosing fabrics for projects.
Letting someone with one fabric needing cutting go ahead of you, just means you can look for more fabric. We are a very friendly and helpful bunch when we shop.
