Here's my version of the granny stitch fat bottom bag ... The Fat Bottom Stash Bag.
Stylecraft Classique Cotton and a 3.5mm hook.
It started out as a giant dc (UK tr) granny square
30 rows in total
To create the top of the bag, I did a sc (UK dc) into one of the corners, then working right to left, I did a sc into the top of the second stitch of the granny cluster followed by a sc into the space in between clusters. And so on across that side of the square and for a total of 11 rows. This created a nice gathering.
I did the same to the opposite side of the granny square.
I then set to work on the sides of the bag and the handles. ** To do this I did a sc into the corner and right to left, a sc into each space between the clusters.
When I got to the top, I sc along the side and then chained 60 to create a handle, attaching it to the other side of the top of square with a sc. I then sc along the opposite side of the top. **
I repeated ** for the other side of the sqaure.
I then went on to sc around for a further 10 rows.
I didn't line my bag as it's just be for my crochet WIP ... yarn and a hook case. If I had wanted to line it, I would have done so before the gathering stage.
