I find myself making more and more of Rosa's clothing, especially as I grow confident with knits. It sounds so grand to say that I'm "confident with knits," though really it's nothing special when you consider how forgiving a fabric it is! *wink* At any rate, leggings have been coming off the assembly line lately, since I find them perfect to pair with tunics and dresses that are now a little too short. Also, I can usually fit a pair on the leftover fabric from one of my tops, so the fabric is generally free.
I usually keep it simple -- a two-piece pattern with a hem at the bottom (sometimes pre-provided if I'm using an existing shirt) and a casing with elastic at the top. It's almost shamefully easy. The middle pair below has my favorite waistband, namely, a waistband casing that stitches right-side-together to the leggings and is topstitched down. It just looks so tidy!
The pair on the right was made from an incredibly soft Old Navy top I thrifted for $1 -- it was hopeless for me, but perfect for leggings. And I was even able to salvage the adorable double-layered, bobble-trimmed cap sleeves to use as ruffles.
Simple and gratifying. Now that's the kind of sewing I like!
