urgodschild2--If you have time to start now, getting the first 3-4 blocks done would be a great idea. Then when you return from your trip you will be ready to start. If you don't get them done, you can always just catch up through out the year.
I did some figuring today and need to make 10 extra blocks (using some of the "combo blocks" shown in the beginning of the book). I'll be making 2 quilts (10" blocks) 5x6 layout, plus sashing and borders.
