Camera Cozy

[littlemiss83]

I want to create a cozy for my camera and 2 outside pockets for my batteries and sd cards.
How do i know how much i have to knit for it to fit my camera properly ?
Is there somewhere where we can see if it is 10 cm big how many rows do i have to knit on what sized needle ?

hmmmm.... sometimes you just have to hold it up as you go and compare. Another option is finding a pdf pattern for cheap. There are a lot on Etsy for cheap. Goodluck!
