A tutorial with photos to construct a lined, flat-bottom drawstring project bag for knitting or crochet. Finished project has a four-inch square bottom and is seven inches tall, though dimensions can be easily changed. See end of pattern for tips to make it reversible.
[Update: the pattern calls for 3/8 yard of two fabrics; two fat quarters will work also, and you'll have less waste.] from the designer's website: https://yarnenvy.blogspot.com/2006/04/how-to-make-my-leetle-bag.html
