Attention, dog lovers or the Martha Stewarts with a soft spot for animals!
Here's a DIY date idea... Make homemade doggie treats! As a date, go the grocery store together, pick up the necessary ingredients and then work your magic in the kitchen. That is unless, your kitchen pantry is already stocked. Per @IslandDogGear's suggestion, try out one of the many FREE recipes online (click HERE).
Even if you don't have a "man's best friend", you two can bake some and take it to a local dog shelter. Or better yet, volunteer at Karma Rescue's pet adoption events (see Cheap Date Idea #53 for more info). The next events are scheduled for March 20th and 27th. I'm sure you two will make some new best friends with these homemade treats.
However, if you want to bake something for human consumption, try out Cheap Date Idea #112: Williams-Sonoma offers FREE Technique Classes. The next few are part of a baking series, where cookies are the next one on Sunday morning of March 14th. No matter what you do, be creative and have fun with your partner!
Approximate cost of creative date idea = Minimal for baking ingredients.
Actual value of the cheap date idea = Priceless + Good Karma.
