What colorway are you going to use? Baby yarn or worsted? Variegated yarns often look better with simple patterns because the details in the yarn can hide the stitch pattern. Depends on the yarn though.
I love Comfort! I make most chemo caps out of it and am making a sweater for myself. It can be a little splitty, but that doesn't bother me.
If you click on this link You can choose from a bunch of free patterns.
Or on Ravelry you can look for the yarn and then look at what people have made with it.
