This is what I sported on my nails today. :)
Step #1: Start with all white nails.
Step#2: put some of your orange polish on a piece of paper or plastic (I prefer a ziploc baggie), and dip the corner of your sponge into the polish. (another tip, cosmetic sponges don't work for me, I use a sponge used to wash cars.)
Step#3: Sponge the orange onto your nails, focusing on the middle.
Step#4: Repeat steps 2 & 3, using yellow polish. Focus on the tip. Make sure to blend well.
Thats it! Put your top coat on to even everything out. :)
