Make friends with the lessons, limitations, boundaries, and structure.
When there is a fence around the school yard, the children play up against the fence. When there is no fence, the children play close to the door.
I can't remember where I heard those words, but I find them affirming and applicable to weaving. If someone came to me and said, "I want you to weave me something. I don't care what it is, just something you feel like making. I am in no hurry, whenever you get around to it. I want to pay you, so whatever you want to charge me is fine. As for the color, I'm happy with whatever you decide", do you think I will ever make that weaving? But if someone came to me and said, " I want a scarf 9" wide by 74" long. I am allergic to wool, and my favorite color is blue. I need it to wear on my trip in 3 weeks, and my budget is $150." This series of boundaries is "The Problem". Solving The Problem is creative.
Whenever I find myself having a bit of a creative block, it is usually a sign that I haven't built a good enough fence. There is a bit of a knack to thinking in terms of solving problems and to be constantly creating problems to solve.
