Grab some wood cooking utensils at any store. I actually picked these up at Target. You want a wide flat surface for the handle so you have more area for your colorful painting.
The other one got stripes in bright yellow, wild green, and citrus green. Again these are all Crafter's Acrylic paints from DecoArt.
Just use masking tape and mask off areas of your spoon. Apply multiple coats until you get the coverage you are looking for. I stood my spoons in a mason jar while drying so I was able to paint front and back at one time.
When painting is complate, remove tape and paint the portion in between colors with your third paint. Again apply as many coats as needed to get the look you desire. Notice how I kept the paint far away from the actual spoon end of the utensil. These paints are not food safe and should not be placed into contact with food. Also, you can spray your handles with a spray sealer such as the Americana Sealer/Finisher for a more durable finish (my personal favorite). However, these will not be dishwasher safe.
