If the afghan size is unimportant, larger needles with heavier yarn; e.g. instead of a size 8 needle, try a 10 or 11. The resultant knit fabric will have much the same feel. Knitting a heavier yarn with the same smaller needles is possible, but will result in a tighter guage; a less supple and more dense afghan.
