The blue pair are made from a very lightweight stretch denim, and are finished with twin stitching. I used two different colours for the twin stitching - yellow and hot pink (although the colours don't show up very well in the pic) - to give them a bit of edge.
The pink pair are made from a plain cotton jersey. The flower is hand embroidered and adds a little girly touch (as if the pink wasn't girly enough...)
Again, more twin stitching on the hems and waistline. I've done a few project now with the twin needles here and here and I am definitely improving in my technique. And learning a lot along the way.
I signed up for My favourite February challenge which was sewing with knit fabrics, check out the others signed up for more stretchy goodness.
