What a great idea this is! I've recently purchased a Brother SE400 emroidery machine, and I think this project wil give me a good reason to practice using it. I'm also in the process of making dresses and blouses for my 8-year-old granddaughter....a secret pocket sounds just right for her!
And what about using this technique to add a pocket to the inside of a purse or backpack? No zipper! Leave me a comment with suggestions of how you would use a secret pocket. Hope you enjoy :)
