Recently I have become a great fan of circular yoke sweaters. I don't do colourwork, just plain stockinette or reverse stockinette works for me best.
Here is another example. Two yarns held together, one is some mohair-wool-polyamide blend, unknown yardage but I think it is about 100 g/800 m and the second is laceweight wool 100 g/1450 m. Love the combination.
