Time for an oil change!

I found these lovely bottles at Ross for $2.50 each. My plan is to make basil olive oil. When local tomatoes arrive, just picked from the vine, bursting with sunshine flavor, juicy and sweet, I want to be ready with scented oil, fresh mozzarella and grilled crostini.

Have you tried making your own flavored oils and vinegars? I have a few recipes but tips from friends will be appreciated. Thanks.
