This colorful masterpiece is based on a Dutch pattern. They had a great idea to use a ready-made canvas bag as the inner liner, instead of making a new one from scratch. You can use this idea and try to match an existing canvas bag of the right size or adjust the number of stitches to match your project size to the liner you have. This design is strongly reminiscent of the old schoolhouse Apache Tears design. A ink to the free pattern is at the end of the post.
