Step 6: Complete the screen
Taking the lighter gray fabric, fashion it into a square in this same way. I was aiming to have an 11"x11" square to border the 9"x9" screen.
After this light gray is all set, take your screen and, using Steam-A-Seam along the edges, steam it to it's border.
Use some chalk, and more formally sketch out the marks on the dress where you want your screen. When it's all set do the same thing, and use Steam-A-Seam along the edges and iron the completed screen to your dress.
