We use them all the time at work, and I am constantly stocking our house with aromatherapy stuff (i.e. "Sid", my teddy bear stuffed with lavander and a bunch of other herbs who can be put in the microwave to be warmed up!), or hot tea (I like the fruity flavored ones), or those weird giant squishy koosh ball things that are shaped like various bugs that you can squeeze over and over and over. However, I think this one is my new favorite: I just found a website where you can personalize your own adult baby blanket!! You get to choose which type of fabric you want for each side (swirly, fluffy, soft, etc.), if you want a silky/satin border, and they can embroider it for you!
Seriously, I am in love.
