Valentine’s Day is fast approaching, and what better day to show your female co-workers that you appreciate them? The 14th of February is traditionally celebrated by couples all over the world, but it can also be a day to celebrate friendship in the office.

Before sending gifts to your co-workers, check your company’s culture and see if your workplace celebrates Valentine’s Day. Also, make sure to give gifts that won’t send mixed signals, and in this case, affordable yet thoughtful gifts are the key to gift-giving this season.

Here are a few thoughtful Valentine’s gift ideas for female co-workers.

For the co-worker who loves to plan her day

Get her a colorful desk planner, such as the weekly desk planner with tear-off sheets from Rifle Paper Co. ($12). It’s available in various designs and colors that your co-worker will surely love.

For the co-worker who still sends handwritten notes

Some stationery pads with matching envelopes would make a great gift for the co-worker who still sends out thank you notes to everyone. SLoffice has letter sets with envelopes in assorted colors for only $9.99 on Amazon.

For the co-worker who walks to work

Give her a folding umbrella, which will protect her from sudden downpours. Amazon carries mini folding umbrellas in various colors and designs for only $7.

For the co-worker who loves tea

Do you have a co-worker who hates coffee but absolutely loves tea? Then get her a box containing different varieties of her favorite brew, such as Taylors of Harrogate Classic Tea Variety Box ($10.92 on Amazon). This would also be a good gift for a supervisor or a manager.

For the eco-conscious co-worker

Reusable shopping bags are a great gift for the co-worker who cares about the environment. Amazon has shopping bags from Delicol that folds into a strawberry with a draw cord ($3.63), and it’s so inexpensive that you can give one to each of your female co-workers.
