Waves and Wild - Wonder Undies PDF Sewing Pattern

$145.60 per metre
From $17.50
Tax included.

Underwear made with the Wonder Undies pattern are cozy and simple to sew. Once you've worn Wonder Undies, there's no turning back!

Briefs and shorts both come in low-rise and high-rise variations. For the waist and legs, choose jersey or elastic cuffs/bands.

For some parts, an overlocker or serger will produce the neatest finish, but crucially, a sewing machine is all you need for all options.

For Wonder Undies, four-way stretch jersey works best.


  • Available sizes for XXS - 7XL. Waist from 61cm (24") to 145cm (57"), and Hips from 84cm (35") to 160cm (63").

Skill Level: Beginner

Recommended Fabric: Light weight stretch (knit) fabric with a minimum of 50% stretch (ideally the stretch should be 4 way, but 2 way is acceptable). Bamboo-Lycra jersey and rayon-Lycra jersey are beautifully soft but not great for bands so should only be used for the elasticated options. Cotton-lycra jersey is the easiest option for beginners and makes great bands. Good stretch and return is especially important for the waistband.
