Probably the most basic knitted cap is a simple ribbed cap. This pattern is based on a Knit 2 Purl 2 (k2p2) rib, and shows two variations. For a turned-up cuff as shown in the navy cap, you should choose a rib that looks the same on both sides. This one is k2p2.
The white and purple caps are snug beanie-style hats, with k1p1 ribbing tight at the edge, and a k2 garter2 rib for the body. The purple one adds contrast stripes.
To work back and forth, cast on one additional stitch to allow for seam, and end right side rows with a knit stitch. Your seam will incorporate half a stitch on each edge and a 2-knit rib will remain. The seam will show when the cuff is turned up but will be very narrow.
Work in a 2x2 garter rib pattern until the total length of the cap is 5 to 6 inches. The stitch pattern is as follows:
Round 1: K2 P2 around. Round 2: Knit. (purl if working flat)
To get a smooth line at the color change, without the interlinked look on the purl ribs, knit all stitches the first row of the new color. Even in a rib pattern, this will not disturb the lines of the ribs. In the garter rib pattern, of course, the color change should be made on Round 2, which is already all knit.
First decrease round (in Garter Rib, this should be done on Rnd 1): (K2 P2tog) around. (end K1 when working flat)
Work 5 rounds of pattern as established.
Decrease round: (K2tog, p1) around. (ending K1 when working flat)
Work 3 rounds in pattern as established.
Decrease round: (K2tog, P2tog) around. (ending K1 working flat)
Work 1 round as established.
Decrease round: K2tog around.
Break off yarn and run it twice through the remaining stitches, pulling the hole tightly closed. Seam up side if working flat.
