Casting On Entrelac Pillow

The swatching process is over, and I am about to cast on for my entrelac pillow.  The pattern called for size 10 and 10 1/2 needles and then gave gauge information for the smaller needle in stockinette stitch.  Since I acheived gauge (12 sts = 4") with size 8's, I will use those for the smaller and size 9's for the larger.

The pattern is the desert-duel chenille pillow from the Winter 2004 issue of Cast On magazine.  Mine is more of a ocean-duel since I've changed the colors from earthy tones to bright blues -- Lion Brand Thick & Quick Chenille in Royal Blue and Lion Brand Homespun in Montana Sky.
