Ready to bring the artist out in you!
I like to make simple, sleeveless dresses to go with many of my favorite jackets. A cotton dress will hang nicer and resist wrinkling if it is lined. To make a lined dress, I cut the lining using the dress pattern pieces an inch or two shorter than the dress and disregard the facings. Sew the dress fronts and back together at the shoulders; repeat with lining. Sew the lining to the dress at the neckline. You can individually "pillowcase" the armhole seams, then open and sew the side/lining side seam in one.
A tie has many usable parts. There is a piece of fabric at least 3" wide and 45" - 50" long, 2 finished ends that can be used as prairie points, usually a label that can be used as an embellishment, and sometimes an additional lining that can be pieced with others to line small items. A demo attendee suggested using the interfacing to cut headers (stiffener) for armhole seams.
