I usually have more than one going at a time, usually 2-3. One is usually at the point where it takes concentration and good light. It's my early morning project. Another is at the point where I can watch TV or a movie and do laundry at the same time. Another may be at the final point of handwork that I can work on at night when I am winding down the day. Then one day I'll reach a point and work like crazy to finish them all up so I can just start all over again.
