If you do a google, using "bleach bottle purse" +instructions
you'll find at least one site with the instructions.

My mom did them! Cut the bleach bottle (carefully) just below the ridge where the handle ends. Use a hole punch (for paper), it will take a little effort to use, to punch evenly spaced holes. Use about a size g or h crochet hook and worsted weight yarn. Start with a row of single crochet, then I think mom used double crochet the rest of the way up, then ended with a row or two of single, or any edging you like. Make a chain for the drawstring. Weave it thru the top, just a few rows below the top.

I had forgotten all about these! Thanks for the memory.
