Ideal gifts for a girlfriend include yoga mats, spice jars, sheet sets or a spa day. These gifts convey that the giver knows the recipient's interests and wants to give a customized birthday gift.
Yoga mats that are easy to carry in small bags or mats that fold easily may work well for women who are always on the go and don't want to carry a large workout bag. Decorative spice jars are an ideal gift for a girlfriend who enjoys cooking. Sheet sets are a personal gift that can reflect a woman's taste and send the message that she deserves to relax every now and then. A spa day makes a thoughtful gift for a girlfriend who likes to be pampered, including treatments to promote beauty and tranquility.
