First, I would like to bounce happily and say that I am working on my first pair of socks and very successfully knitting and turned my first heel. :woot: It was magical and strangely easy! Now for the gusset and the rest of it, but I feel I’m in the clear. 
Now, for the matter at hand. I needed a new knitting project and I found a pattern for a dice bag. My boyfriend is loaded with dice and counters, but he keeps them in a zip lock bag, so I thought I could make something schnazzy. So I found a pattern for one, which is linked below. Unfortunately, it’s far too small.
I really like how this one works, but I’d like to double it in size. My first thought was to double the cast on, but since it’s so much decreasing, I didn’t know how to go about doing the math.
Can anyone give some pointers? I’m completely lost on this one.
Thanks!
