I have discovered a downside to knitting in the round. It is crap for intarsia, picture knitting. You knit your new colour accross and it is on the wrong side of the picture when you get to the next round.
If you want to put a picture on your hat, knit on two needles.
Feel free to use my pattern for a simple two needle 8-ply beanie on the CPSU Beanie link.
And don't bother with the Patons Winter Warmers Pattern unless you want the brim to fall into your eyes.
