This is a drawstring bag and zipper bag it was a free mini class I learned to do at craftsy it looks complicated but is super easy to make and fun.
that website is from joann's fabric store and they have multiple classes, sewing, knitting, baking....
you can get advantage of the free clases and also you can pay for any specific class you would like to take.
you can also purchase the same supplies that the teacher is using online or used what you have at home, you can also print the materials you would need from there website, so I totally recommended and look forward to make new projects with them, will definitely keep you post it.
