I've been looking and searching for some really inexpensive trinkets to add to a basket. Just find an inexpensive basket and fill it with some things like the ones listed below. Add your favorite bubble bath, shower gel or body scrubs to the set along with a really nice towel. If you have extra time or money maybe you can get the towel engraved with their name or initials.
Here are some things you can put in a basket and give to your friends. All these items can be found at Pier1 Imports for under $20!
