Hope to have a picture soon--but the reversible wall hanging for my daughter took well over 500 hours....and it is just about 36 x 45...it took nine years, as I had a wreck just after I started it, and could not use my hands to sew for quite a while.
For an easy pattern, look at Georgia Bonesteel's books. She has some that are pretty simple. You could do a rail fence or log cabin, or attic windows.....
Lucy's Locket is pretty, too--have you been to Quilter's Cache?
Hole in the Barn Door is another.
