We made a list of all the things we wanted from an undies pattern like 'enough rise in the front (and the back)', 'cheek coverage', a 'wide gusset' and also to avoid a wedgie in the back or a camel-toe in the front. Since no pattern existed to check/tick all those boxes, here we are- the Muna and Broad Waratah Undies and Period Undies pattern.
The pattern includes 3 views: 'normal undies' with Fold-over Elastic, 'normal undies' with Picot Elastic, and 'period undies'
Leila has popped some videos up on the Youtube channel to help with the undies!
Undies Fabric Requirements
You'll need to use fabrics that have 4-way stretch and great recovery for the normal undies and the period undies will require wicking fabric (such as merino), absorbent fabric (such as flannelette) and a barrier fabric (such as PUL)
Pictured below is our period undies- the gusset on this view of the undies is much larger in order to ensure that they're 'leak-proof'!
Here's a video about selecting fabric for your normal undies and there's another video here which covers selecting period undies fabric.

How to find supplies for your period undies
For the wicking and waterproof fabric needed for the period undies, I had some success searching for 'nappy making supplies' (since these fabrics aren't necessarily stocked by places selling lingerie trims).
Check out the product page for the undies for more suggestions about specific fabric names to google because if a store is stocking PUL fabric then chances are they're probably stocking most of the other fabrics you'll require for this view too!
