This is my adaptation of flat front/elastic back flares for Maya. My pattern has a curved front waist piece, and the back is all in one. Please ignore my well loved cutting mat, lol


First, sew/serge the two back pieces together. Cut elastic to fit- I normally do about 3/4 of half of the waist- so, for Maya, who has a 21" waist, I use between 8-9" of elastic. Serge the elastic to the back waist.


Tack the elastic to both ends



Sew on the front waistband, and topstitch


Put pants together, right sides facing, so that the back elastic sticks up about the top of the front waistband.


Fold the elastic over the front waistband, like you are closing an envelope



Serge from the bottom of the leg, up to the top,

This is how it will look after you serge:




Flip elastic


Turn pants right side out & topstitch elastic, I normally do three-four rows of elastic.
