One of the easiest lace patterns for lightening up a solid fabric is Purse Stitch.
Here it is in its entirety:
On an even number of stitches,
K1, *yo, p2tog. Repeat from *. End with k1.
Every row is the same.
I've used this on the yoke of a worsted weight cotton sweater and it worked out well. But please take Jan's advice and do a swatch to see how it will look in your yarn.
