I am in the long process of making a Dear Jane, and like some of you suggested I leave it by my seat and work on it at night while "watching" TV. Most of them I have hand pieced and a few I've paper pieced, and so far I've completed just over 50 blocks and 1 triangle.
If you go to the Dear Jane site there is a section on block and triangle tips that helps with piecing. This feature is also on the EQ version under Home/The Blocks/Block Tips. Under the same section there is also a listing of all the blocks and their difficutly level (some of which I didn't agree with, but oh well).
