Why is my ball not turning in to a ball?

[loopylooper]

This has happened for the second time with my last pattern. It's not the pattern it self as  others have done it correctly. When I go to decrease it turns in to a hat rather then a ball and the ball doesn't sew up as the hole is too big. What am I doing wrong?

Hello again!  A ball IS going to look exactly like a hat for about two-thirds of the way through.

You start by increasing to make circle for a while (like a hat), then working even (meaning, without increasing) for a while (like a hat).  But when you start decreasing (which is where you say you are having a problem), it should cease to be hat-like.  You keep decreasing at the rate it tells you to until there are only a few stitches left (usually on the order of 6-8 or so), then gather up the stitches to close the ball--this usually involves cutting the yarn leaving an end to gather and sew it up with the yarn tail and tapestry needle.  And, presumably stuffing the ball maybe a round or 2 before that point.

Are you marking the beginning stitch of each round?  This is really important when you are working in a spiral, trust me there is no way to 'know where you are' if you don't; I probably said that in your other post, but it bears repeating.  Also it probably would be a good idea to double check the stitch count of every round, before you start the next.

Hello yes I am marking each stich at every new row. I'll show you the pattern. What I can't understand is it has more rows for increasing then decreasing and im getting confused

In your other pattern for the cat's head, the head as designed was not a round ball either, according to the pattern photo you shared.  What you had made matched the pattern photo for the in-process head at that point.

Does this new pattern give you a summary of the stitch count at the end of each round?  (not all do, but it is a very helpful feature). Is it possible, like the cat, that you were expecting it to be round, and it isn't?  It's possible that it increases at one rate, and decreases at a different rate; imagine a shrew's head, which has a long pointy snout for (an extreme) example; if you started at the top of the head you'd increase in a few rounds quickly for the area where the eyes are, then decrease over many rounds gradually for the snout.

How many stitches are in this 'too big' hole?  In the cat's example, it wasn't nearly too big to close up, when you thought it was.  You can gather a lot of stitches together to close up a hole.....just like you can put a lot of stitches into 1 stitch.  Crochet fabric is pretty flexible.
