I used a J hook for these
I really wanted to do some granny squares, but really didn't feel like making a blanket, so I made a couple of bags, I like the larger one to use for beach stuff etc....These could be very easily lined with fabric to make a nice bag to hole some of the smaller stuff too.
These are just a few basic granny squares turned on their sides. For the blue and brown bag I used three squares done in 8 rounds. Bottom square foled in half, I pieced together by folding two more in half and attaching two sides making them look like triangles... It's easy to see in the pictures if you need help leave me a comment. I didn't make the strap very long as there is a big gap in this one.
I made straps by making a long chain for what I wanted for length, hdc around both sides and then sc around for the second rnd.
For the Green and yellow bag I used four (only 6 rounds on this one) squares and attached as the larger bag and the fourth one I filled in the triangle in the back and used as a flap. I added two more rows to the top side for it to come down over the front of the bag and attached a button to fit through one of the corners. Would love to see any pictures if you make one or two or more! :o) Happy hooking.
