I'm all over the place. I usually start out cutting down the fabric into the strips needed to create the different units. I keep those separated by unit in plastic bags. From there I start working on one unit at a time. Sometimes I get bored and then switch to another unit. Then I decide I want to see how the block looks and finsh those up. Then I decide to systematically finish unit by unit, joining those units to make the blocks.
I do usually finish my blocks before joining the quilt top.
By then I am bored with the project and the quilt top sits until I am bored with something else and find the project and wonder why I never finished it.
Can you spell ADD?
