My version of the wooly bowl and a question.

I decided I wanted to make a little pot with a lid, and I had some left over to make a low sided bowl/tray.
Here are my attempts

So the two smaller ones fit together.

Bright aren't they LOL!!

Here is the link to the lady I bought them from at the show.

Now for the question
Does anyone know how I makes the sides on this to make it into a bag, I was originally making a granny square, but added another cluster by mistake, but liked the shape. But I want to do sides up but I am not sure on how to go about it!

I want to make a bag for my wool.
