In as many shade variants of flower color as you have handy, duplicate stitch is a very simple way to add not only a spot of color, but varied spots of different colors, making the flowers really pop out, and look so much like a real meadow. Use different shades of same yarn, or similar weight of other wool yarns, even a couple of strands of crewel wool will do!
Step 1: Thread tapestry needle with contrast color. Step 2: Bring yarn forward from back of work, through base of stitch you are overlaying. Step 3: Follow stitch and thread yarn behind base of stitch above it. Step 4: Bring yarn back through base of stitch, to back of work. Step 5: Move on to next, changing colors randomly as you go. Tie off in back and cut short, do not weave in ends.
Here is a photo slideshow of the process. Easy!
