The drawings of KC designer Nelly Don’s patented zero-waste apron, so intrigued me, that I committed myself to working out the measurements and construction process for the apron. My post last week about Nelly Don and her apron design (including a downloadable copy of her 1925 apron patent) is here.

And now, for the measurements and steps to cutting out the apron…
The 1925 patent diagram shows a single layer of fabric. For my apron, I concluded the fabric needed to be 48″ long and 36″ wide (1 1/3 yds x 1 yd).

Drawing the diagram. Start with the measurements across the yoke and work out the rest from there.
From there you can work out the width of the side panels, and the front and back pieces:
Here’s the process in a step-by-step slide show. If helpful, it can be viewed on Youtube in full screen; pause and rewind as often as necessary.
For shaping the simple round neckline in the yoke pieces, here is a pattern you can download and print on an 8 1/2″ x 14″ (legal sized) sheet of paper:

I tried some different dimensions and measurements for the apron layout, but the version I’ve described above is the only one that really worked. Some problems I encountered when varying the dimensions were:
- Narrowing the yoke width also means the side panels become narrower, which makes the side pockets too narrow to be useful.
- A longer/lower yoke meant the side panels became shorter, which made for a shorter apron; which then made the A-line angle more exaggerated. Alternatively, if the hem length were maintained, it made the side panels sit too far below the waist, or not extend all the way to the hemline.
- A shorter/higher yoke made the side panels longer, which made them come up higher to the waist. This made a smaller, tighter waist because the front and back pieces are narrower at that higher point where the waistline is located.
So, there you have the apron pieces. Nelly Don designed the pattern so that the entire apron could be constructed without ever having to remove it from the sewing machine. I’ll tackle that in the next post…
