I use 1 inch strips sometimes. It depends on whether I am using a foundation (thin old sheet, ultra light fusible interfacing or something else) The foundation helps to keep the strips from stretching and bowing, but also allows me to use a 1/8 inch seam on the strip I am attaching. I lay the thinner strip a tad to the left so that when I sew, it will have the 1/8 inch seam allowance but the strip underneath will have 1/4 inch. I also make a point of shortening my stitch length. The narrower seam allowance will be enclosed which will protect it from raveling.
