I made some shoe bags for Christmas, which is a nice way to use up scraps.
I like to press the casing while everything is still flat. I folded the top edge over at 1¼” and pressed, then folded the raw edge in to the fold and pressed.
One side is on the fold. The other side and the bottom are french seamed. Finished dimensions are 10″ x 14″.
I cut the drawstring 36mm wide to fit through an 18mm tape maker; final width is 9mm/ 3/8″.
Fabric is Michael Miller Luna Moth in turquoise (bag) and raspberry (drawstring).
