After searching high and low for a suitable beret pattern I was pointed to this pattern:
http://www.thegarterbelt.com/wb_lastminutepurl.html by a few people so I took that, added some simple cables and kinda winged it and ended up with this:

close up of side/top & cable action

It's made out of Misti Cotton (
http://www.mistialpaca.com/catalog.php?collection=9&page=0) in Eggplant. It's 83% cotton, 17% silk, & dreamy to knit with. I think I'll have to make a wool one when it starts to get colder though!
Here's my modified version of the pattern!
I used a set of 5 US size 9 DPN’s (5.5 mm). You may want to use a size smaller for the ribbing so it stays on your head better. Oh also, if you decided to cast on less stitches (72), you won't have enough to do the last cable round.
CO 80 stitches and divide evenly among the needles (20sts) each. Place stitch marker every 10 sts. (I just put one in the middle of all the sts on each needle and think of it as an imaginary marker when I switch needles. Make sense?)
Join in the round and work in 2 x 2 rib for 8 rounds.
Row 9: (Increasing) *K2, M1; Rep from * to end.
Row 10-15: Knit
Row 16: *CF6, K to marker; Rep from * to end.
Row 17-23: Repeat Row’s 10-16
Row 24: (Decreasing round 1) *K3, K2tog; Rep from * to end.
Row 25-29: Knit
Row 30: *CF6, K to marker; Rep from * to end.
Row 31: (Decreasing round 2) *K2, K2tog; Rep from * to end.
Row 32-37: Repeat Row’s 25-30
Row 38: (Decreasing round 3): *K1, K2tog; Rep from * to end.
Row 39-43: Repeat Row’s 25-29
Row 44: CF6; Rep to end
Row 45: (Decreasing round 4): K2tog; Rep to end.
Row 46: (Decreasing round 5): K2tog; Rep to end.
Row 47: (Decreasing round 6): K2tog; Rep to end. (6 sts remaining)
Leaving a 12 inch tail, cut off yarn and draw through remaining stitches. Pull tail through to the inside of the hat and pull tight & fasten. Weave in ends with a tapestry needle.
