It started with a photo of a blanket I saw on Instagram, that someone had made of Mario...you know, the dude who used to fight Donkey Kong by jumping over barrels, and then made it bigger than the Kong himself. Anyway...my kids are into Minecraft....
We decided on this:
As you can see, it's no biggie graphing this - all it takes is working out what colours you are going to use, what size you want, and off you go. I should point out that I'm making the blanket in granny squares. There are a hundred altogether for the main pattern, plus as many as you want in a border colour (I'm thinking a really dark green).
Wish me luck! Hopefully I'll remember to take some pics of my work in progress!
