Ok well I was following a pattern and it said to sc 1 in the next four sc and then sc 2 in the next one. I don't think I increased. I was just counting and going around and around and bah.
When you sc 2 in the next one, that's an increase, because you're doing two stitches in the place of one. The basic pattern for flat circles is this:
Do a magic loop. (tutorial
Row 1: 6 sc
Row 2: 2 sc in each (12)
Row 3: *1sc, 2sc in next*, do this 6 times (18)
Row 4: *2sc, 2sc in next*, do this 6 times (24)
Row 5: *3sc, 2sc in next*, do this 6 times (30)
Row 6: *4sc, 2sc in next*, do this 6 times (36)
etc, etc, increasing number of initial sc's each time you go around.
You want to do six increases on each row, but you need to space them out as the circle gets bigger. If you just do an increase every four stitches, that's going to be more and more increases each time, which is probably what happened.
Now, when I do hats, I start from the bottom. I chain something long enough that when I join it, it fits nicely around my head like I want the bottom of the hat to, then I sc around until it's long enough that I want to start making it slope towards the top (about 3-4 inches, depending), then I do this:
Row 1: *10sc, 1sc in next 2 (this is a decrease because it's one sc in two stitches)*, repeat to end of row
Row 2: *9sc, 1sc in next 2*, repeat to end of row
Row 3: *8sc, 1sc in next 2*, repeat to end of row
etc., until it gets really tiny and I just kind of fudge the end. You can't follow that pattern right to the end of the hat, unless you want the end to be really pointy. On my last couple of rows, I usually decrease a lot, sometimes doing one sc in 3 or 4 stitches.
Hope that helps! And hey, don't despair about your first attempt -- it's close to the crochet version of a Lorenz equation
