Sew a Custom-Sized Drawstring
Dust Bag and Gift Bag

Convenient, Accurate and Versatile — this is a revolutionary, must-have tool unlike any conventional sewing pattern you’ve previously used.

Sew an easy, custom-fit drawstring pouch regardless of your sewing experience. Fit Without Fail is the ultimate web-based pattern calculator designed for beginners and seasoned sewers alike.

Why is Fit Without Fail so unique?

  • You are not limited to a Large, Medium or Small size.
  • You do not need to determine the finished dimensions of your dust or storage bag. That size, including the required ease, is automatically calculated for you.
  • Simply enter the height, width, and depth measurements of the item you wish to cover into the intuitive calculator and instantly receive the precise cut dimensions for your chosen fabric including the drawstring length.
  • The step-by-step sewing instructions are designed to make the sewing process a breeze for everyone.

The possibilities are endless with Fit Without Fail’s finished drawstring pouch!

  • Embrace a stylish and sustainable storage solution using your pouches as dust bags to protect your designer- and custom-made handbags, backpacks, and other valuable items.
  • Fit Without Fail pouches are the perfect “giftwrap” for unusually shaped items, adding a personal touch to any present. Say farewell to wasteful paper wrapping and welcome a reusable and eco-friendly alternative.
  • Embrace the power of home organization, too. Keep your home tidy by using them for children’s toys, seasonal clothing storage, or any other clutter-busting needs.

    Happy New Year! I love the ease of the formula worked out for me so I can make one or dozens with ease. I purchased long shoelaces for the drawstring and I’m willing to make covers for past and future bags without grumbling! The most practical purchase in bag making. Thank you!

  2. Maggie

    I’m not saying I couldn’t work out how big to make a dust bag for my products but this is so easy to use! Just pop in your bag sizes and it does it all for you. Absolutely ingenious!

  3. Eve (verified owner)

    Customers love getting the dust bags with their purchase and Fit Without Fail makes to almost automatic to add. So easy with the perfect made-to-measure formula. A sewing friend said, it’s easy, why would you use that? She obviously has not made multiple covers in many sizes to realize that it takes too much time to custom calculate and is not always accurate when it’s DIY. This is a terrific resource I use over and over. Well worth the price.

    Love everything about this. Wonderful tool, that is fail proof and works every time. The result? A custom, gorgeous dust bag that has elevated the quality and value of my bags. Thanks, Patty for such a great product.

  5. Peg Coombes (verified owner)

    I’ve only made a few but it’s perfection! every time, takes the guessing out of trying to make my own

    So worth the money and instructions are great

  6. Susan (verified owner)

    I discovered this software at the perfect time. My niece was taking a purse I made for her daughter as a gift via airplane. So, I wanted something more than a regular gift bag to protect it. So, I input my purse measurements and it gave me my measurements to cut my bag. It worked perfectly and I think I will be using it often.

  7. Susan Shaw (verified owner)

    I love this so much I’m on my second bag already. The instructions make this so easy to make. I LOVE the 1/2″ seam allowances, and how the top is finished makes the bag look so professional.

    Très pratique et utile. Je rajouterai toutefois des valeurs d’unité de mesure comme le cm qui m’aurait évité la conversion

    Very practical and useful. However, I will add unit of measurement values ​​such as cm which would have saved me the conversion
