Semi-rigid two-color plastic and cotton bags

New version of the semi-rigid bags ; this time the white plastic of the shampoo bottle contrasts with the colored cotton crochet.

As always, I cut the bottle to the desired height with sturdy scissors and then I pierced the plastic, around the edge obtained, with the tool used to make the holes in the belts.
The crochet part starts with a single crochet round worked directly into the holes and then continues with a few rounds of double crochet worked in alternating mesh .
