I've never used stripes on furniture before and I was a little hesitant to try. I just used regular blue painter's tape (not the expensive stuff). I painted the coral in the middle. Taped off the sides. Sealed the tape with the coral color and then painted the grey. After a few coats and a couple of days I peeled off the tape and I had a perfectly crisp line. Easy Peasy!
The paint colors are Behr's Creek Bend and Youthful Coral. I just purchased the testers for $3 at Home Depot.
