Intarsia Hell

So I'm I new knitter, right? 3 months and counting. I told my 4 year old that I'd make her the punk rock backpack from the first SnB but of course she didn't want the bunny or monkey face on hers - she wanted a kitty.

Using the knitter's graph paper I made I designed a kitty face for her and figured 'how hard can it be?' Anyway, it's going alright but it's definitely more challenging than I thought it would be.

My advice to other new knitters thinking about intarsia? Start with a square in another square - 2 colors, easy.
