Sometimes the best present costs very little money.
Take a nice picture that you have. Buy a frame that’s bigger than the picture.
Make a backing out of construction paper, and write some nice things around the edges. It can be something that will remind the person of when the picture was taken, or just a nice endearment.
You can also give coupons that you make yourself – “Good for one night of no cleaning up” or “Good for a private walk at the time of your choosing.”
