I made this one a while ago, but its been packed away until now. This is made with 100% cotton yarn and I don't mind saying it was quite some work to get this one done.
The front is made up of individual squares made of 3 different coloured yarns, an ecru, denim & darker blue. they are then individually crochet together to make the front panel - trying to make sure that the same colours aren't together!.
The back is made up of stripes of various sizes, again using all 3 colours of yarn. Same for the straps which are attached into the seam at the bottom & buttoned at tht top.
Then the closure is a simple crochet chain & I've added a couple of chunky beads to the ends.
