Period panties were a pain in the butt to sew before this pattern came along!  The outer panty is just one cut of fabric.  Stick the core on top, sew it down, and you're practically done.  

We've included lots of information to help you make leakproof panties that fit, on the first try.  There are 7 core length combinations for various flows.  An extensive materials chart that includes links to  hard to find fabrics, as well as household materials if you want to get started right away.  We added stepper and keyhole templates for super heavy flow. 

You can even make a cloth pad that is custom shaped to your panty!  

Like our other Bum Hugger patterns, this one is designed for elastic-free leg openings.  

Pattern options: Version A is super high rise with a wider than usual gusset.  Version B is high rise with a more average gusset width.  Version C is a high rise tanga panty!  The core can be centered where a gusset usually sits.  Belly sleepers can make the core go up to the front waistband.  Back sleepers can make the core go up to the back waistband.  For postpartum or heavy bleeder panties, you can use the full core piece which goes from the front waistband all the way to the back waistband! 

Difficulty:  Suitable for beginners!

Fabric:  Horizontal stretch of 60%.  Vertical stretch is not necessary, but will make your panty more comfortable when sitting.  Bamboo/spandex, merino wool rib knit, merino/spandex, cotton/spandex.  The liner can be made from non-stretch fabrics.

Yardage:  Two panties per yard of material, plus core materials.

Special supplies needed:  ¼” elastic for the waistband.

Maternity friendly:  No.

Nursing friendly: N/A

Size range:  11 sizes from XXS to 5X that fit 35” - 71” (89 - 180 cm) hip

Fit:  Negative ease (very fitted).

Time to complete:   Start to finish is about one hour.

About our Patterns


We aim for inclusive patterns that fit all bodies. If you don't see your size on this pattern, send us a message and we'll add it in!

Our size charts offer both metric and imperial measurements.

Seam Allowance

All of our patterns have a standard, 3/8" or 1 cm seam allowance.

Print Internationally

Our tiles have two layers, labeled A4 and Letter. US printers use the Letter layer, and everyone else can use A4!

Trimless Tiles

We designed our tiles to save paper and be easy to assemble. Place the guidelines on top of each other and tape or glue. The letter layer has solid guidelines with a star in each corner. The A4 layer has dashed guidelines with a circle in each corner. Each page has a number, and the tutorial has an assembly chart.

All of our files offer layers, allowing you to print only the size(s) you need.

Copyshop Printing

A0 pages are 33.25" by 60" and are printable at most copyshops. We design ours to be printable in black and white. There are no passwords on any of our files. Our A0 files have layers, allowing you to print only the size(s) you need.

Projector Optimized Files

Every pattern comes with a projector optimized pdf file. See what our projector file includes here.

All of our patterns are drafted digitally and tested with a projector in our paper-free studio.

Video + Picture Tutorial

We use pictures in our tutorials, not line drawings. We add in videos of steps that testers have a hard time understanding.


Our tutorial has a table of contents, along with bookmarks. This allows you to quickly get to the page you need.


When a pattern is updated, you will get an email notification. We allow our testers access to our entire pattern catalog, which means we get continual feedback on our patterns.
