I would also suggest, until you know if you like doing this, to stick as close as possible to your own color. That way when it grows out, it won't be quite as obvious.

I had highlights done in a salon here in the St. Louis area and with cut and set it came to well over a hundred before tip, and this was several years ago. I can't afford that so I'm natural right now. I'm thinking about doing what you are, but just highlights. My problem is trying to convince my husband that he wants to spend an hour pulling hair through a cap with a crochet hook. lol.

If you just have a little gray at the temples, there's a product on the market that you can dab in to cover just a small area. I have no idea what it's called, I just know my hairdresser dabbed some on me one day and it hid my more prominent little gray streaks near my temples. It washed out the next time I shampooed.

Let us know what you decide and how it turns out. I've been chicken so far, so maybe if yours if a success, I will break down and buy a kit.
