Well, I have decided to make a bag out of it, oh yes I have. And for that purpose, it will need a back panel, which is the piece I have just started working on and which I would like to share with you today...
It will be a simple solid granny square in the same colours (nine, in total) as the original square.
As you can see, it is still tiny, and will need a few more rows to reach the other's size. But I'm sure it'll happen soon enough :)
Don't forget to go check the others' work at Jijihook's website!
