Silk organza is a very stable fabric that minimizes bulk in a project. A year ago I bought six yards of this fabric. I have been using it as an invisible layer for different aspects of sewing projects as I learn new ideas.
Back in December I used it as sew-in interfacing for my Lilacs and Liberty shirt. Tonight I cut strips of silk organza on the straight-of-the-grain that I'll be using to stay the top of the inner shell of my bustier bodice. The strips are intended to be 1 and 1/4 inches wide (mine are a little wider at this point in time). They'll be folded lengthwise (resulting in 5/8 inch wide strips). Then I'll cut them about 1/4 inch shorter than the width of each bodice piece, which I'll be easing to the strips with hand stitches. I'll stay each piece of the bodice individually.
Using silk organza makes me feel a little glamorous. It doesn't actually cost much more than other interfacing and stabilizers, and makes me feel like a real seamstress!
Silk organza keeps the enchantment in my sewing!
