Fast-Track Fitting: In the Details
Fine-tune and alter patterns to fit real bodies really well! Go beyond the basics: demystify ease, muslin-fitting, sleeve-fitting and more for a figure-flattering look.

Take your fitting confidence and skills to the next level with new techniques from fashion designer Joi Mahon. Start with pattern-fitting basics: refining your pattern for a custom fit in the torso and lower body and truing up your side seams for easy sewing and expert results. Fitting ease and design ease are easy with Joi's guidance for adding both to your patterns for superior comfort and style. Next, go step-by-step through a demonstration of muslin-fitting and contouring your garments so you can ensure that your final fit will be stellar. Joi will even end sleeve-fitting stress as she teaches you to address specific sleeve-fitting issues, quickly draft your own sleeve pattern and more!

Lesson plan


Lesson 1. About Joi Mahon & This Class

  • Meet your instructor, Joi Mahon, and review the basics of body measurement and altering on the pattern before you sew a stitch.


Lesson 2. Flat Pattern Refinements on the Torso

  • Joi jumps into the finer details of pattern adjustment with tips for making vertical changes on a bodice front, fine-tuning bust fit and tweaking armholes and necklines.


Lesson 3. Lower Body Flat Pattern Refinements

  • Get a perfect lower-body fit on skirts, dresses and pants with Joi's help. Adjust the abdomen and back hip, then true the side seams and adjust hem lengths.


Lesson 4. Fundamentals of Ease

  • A perfect fit includes ease for comfortable movement. Joi demystifies the process of adding the right amount of easy to your pattern, whether it's for comfortable movement or as a design feature.


Lesson 5. Fitting on the Real Body

  • Once you've adjusted your pattern, you'll want to make a muslin to tweak the fit. Learn how to pin, pad and position your pattern pieces on a real body.


Lesson 6. Fitting the Sleeves

  • Do sleeves make you crazy? Get some straightforward fitting tips from Joi that will have you looking forward to getting them just right.


Lesson 7. Drafting a Sleeve

  • Maybe your commercial pattern didn't include sleeves and you want to add them or you have particular fitting issues that you need to address. Why not draft your own sleeve pattern? Joi shows you how!


Lesson 8. Bonus: Frequently Asked Fitting Questions

  • As a bonus, Joi polled her students and Facebook followers to bring you some commonly asked fitting questions with answers! Get quick tips on fitting narrow shoulders, wide busts, narrow waists and ample backsides.

"I am so impressed with this method of addressing fit issues. It makes so much sense to look at the body as four quadrants front and back upper body and front and back lower body. This makes for quick and precise adjustments that work basically the same no matter which quadrant of the body you are adjusting. The sleeve lessons are an extra nice addition as well and address several common fitting issues. All of the lessons are well taught and add to the whole experience. Thank you Joi for another terrific class!"
