I went through my archives and found some cute ideas I posted for Valentines Day last year. I thought they were pretty darn cute and deserved another go around. I don't know if you are looking for any more Valentine's ideas, but here are some hard to resist ideas...
Rice Krispie Hearts...with Chocolate
You haven't had rice krispie treats until you have added chocolate to them. Want an ever better treat...add Nutella on top!
It doesn't get much more frugal than this. Use the oatmeal container...making the above cookies, of course, and re purpose the container for transporting the cookies to your Valentine! Decorate the container with some paper and craft stuff you have on hand and it turns out pretty cute. If you are anything like me, you have a plethora of scrapbook stuff...in a scrapbook room...and you really don't even scrapbook!
