I hand-crocheted a sacoche bag. It's a two-tone color of light blue-gray and turquoise blue. I used 100% cotton yarn. Width: 19cm, Height: 23cm There is no gusset. I crocheted a sturdy shrimp stitch cord for the strap, which is 120cm long. The opening has a flower motif that hangs down from the back. It has an inner lining. The strap is attached with a lobster clasp, so you can remove it and replace it with your own strap.
