It's made of two kinds of squares: one with 21 colored squares and four white, and 
the other of 21 white and four colored.

So I decided to make it with tiny granny squares, making the center nine squares of 
the white pieces all one granny square, and to use a rainbow of colors rather than 
just two.

I got a WHOLE LOT of Sugar 'n' Cream yarn by Lily, in every color that wasn't too 
bright, and also some of the mixed "ombre" colors. For the white parts, I got ecru, 
since I am skeptical of any useful household item that's white. Either it's never 
used or it won't stay white.

After doing a sample, I found that 25 granny squares sewn together measured 18 x 18 
inches, so I decided to make 16 of the large squares, 8 multicolored and 8 white, 
and then do three more rows of the granny square stitch around them to tie them 
together.

With this yarn, a skein of regular, one-color yard made 11 or 12 squares, and the 
'ombre' (variegated) yarn skeins, which were shorter, made 8 or 9. Then I crocheted 
400 granny squares...and now am putting them together. So here's the outline of 
how I did it:

    * Decide how big you want the thing to be, what colors, and what kind of yarn.

    * Make a sample granny square and measure its size. 
        You can make it bigger or smaller by adding or subtracting rows, although I 
        think you need at least three rows for it to look like a granny square.

    * Put the squares together in groups of 25. The squares that are mostly color 
        have the white granny squares in the center of the sides; the squares that 
        are mostly white have the colored granny squares at the corners. You can put 
        them together any way that suits you; I'm whipstitching mine, jsut seems to 
        work better. And I'm using the ecru to do it, even though the stitches show 
        on the dark squares.

    * When you have all your squares of 25 done, put them together for the main body 
        of the afghan. 

    * Do as many rows as you like of the same granny stitch around the whole outside of the 
	afghan to make an edging.
