do opposite sides first then top and bottom. Sides will be 2 inches long by the width you want. I would audition 1.5 sashing to see if you like it. If you did that then the top and bottoms would 5 inches long. Then I would put them in rows of 8 and make 9 rows. Of course, the world is your oyster with these blocks. You can do just about anything! You could make 4 patch out of them, using them as a "film strip" border, and more and more and more....Check out the scrappy quilts here on the board for inspiration.
