Here is my design drawn on the back with a layer of cotton batting between the magic and the silk Dupioni. You sew from the back.
And this is what it looks like after steaming. It shrinks by 30%. I was so disappointed with the look. It just looks like a bunch of puckers and you can't see the design at all.
So I tried the same design without batting. I still don't like it at all.
This is just plain FM quilting with Hobb's wool batting. I like this so much better, I will not use this design on the quilt, but will be using red silk again, although a different shade. What I like about the wool is that it gives a lot of depth. Whatever you don't quilt down really puffs up, almost as if you had used trapunto. I have some designs in mind that should work well.
I haven't completely given up on Trapunto Magic, I just won't use it on this project. I think it might work well in a purse.
