View Full Version : Hat decrease "formula"?

Im making a hat on circulars with wool ease thick & quick. I had found a pattern for 45 sts that started decreases at k7 k2tog. I had to :frog: it because it wasnt big enough, so I cast on 55 sts instead. Is there a "formula" or something for decreases? I was thinking that k10 k2tog would make things even, putting me back where I started. Im also hoping for kinda a "flat" top, kinda like the baby hat here (http://www.knittingonthenet.com/patterns/kidsrollbrim.htm)

I think if you use k10 k2tog you would then have more rows with decreases, right?
But since they give the same addvice on the baby hat, it might be right to do so...
Sorry, I'm not much of a help. :oops:

Of COURSE you are helping! That was exactly what I was thinking....I just dont know if more dc rows is a GOOD thing???

I can't wait to put this thing up on the finished projects page....It's gonna be really cute. It's black TnQ with a smidge of aqua fun fur thrown in around the rolled edge...matches a scarf Ive already made.

Does anyone think that more dc rows is a bad thing?

Hey KellyK!

You don't want to do k10 k2tog, because that will span 12 stitches, and 12 doesn't go into 55

The good news is, 55 is the perfect number to work with, because, like 45, it is divisible by 5, so you can still have a 5-pointed star type decrease, which is what the original one gave you.

The original one had 45 sts, and was k7, k2tog. The first decrease spans 9 sts., which, over 45 stitches, will give you 5 sections, and 5 decrease lines. Hope that makes sense.

In order to keep a similar decrease ratio, you want to keep it a 5-point decrease, so....
55 divided by 5 = 11. You want your first decrease row to have decreases spanning 11 stitches. This means *k9, k2tog*.

This will give you extra decrease rows, but this is GOOD, because your hat is nearly 20% bigger around (18% to be precise), so you also want it to be bigger going up, or it'll be a short hat. In fact, you'll also want to add more rows before you begin decreasing. If your lucky, your existing pattern says knit "this many inches" before decreasing, rather than "this many rows," so you don't have to do any math at all, just knit that many inches. If you have to figure out how many rows, then, let's see.... 18% more rows might be right, but I'm not sure, so do some math and figure out how deep this will be, and hold a ruler up to your head and see if it looks right.

As far as the actual decrease rounds, they should work out perfectly, just decreasing at whatever rate they tell you, but starting with k9, k2tog.

Hope that helps!
Amy
