Very tiny details can often get lost in your embroidery go just be tufts of thread sticking up. One solution for this is to first trim any thread sticking up. Then if it’s a darker thread on light, touch it up with a permanent marker. If it’s a light detail – like the sparkle in an eye, thread a sewing needle with your embroidery thread and put two of three stitches and tie off the thread neatly on the back of the design.
