I cannot start a tapestry unless I dedicate a specific workspace for the project. Everything must be neat, organized with everything in its proper place. I will admit it does not always stay that way once the weaving is in process but I must start with everything in its place otherwise I just putz (spelling?) around and accomplish little.
Here's a photo of how my back studio looked after several days of weaving...yes, it still looks neat and tidy. It was not a few minutes ago... Once I finish a major section (here the blue background on the lower left), I usually clean up the work area again to start a fresh with the next new section.
