Agatha's Blueberry Buckle

It's not blueberry season, and I don't know if you have seen the price of blueberries in the store lately, but they are darned expensive.  I know because I keep checking the price of fresh berries because I have wanted to make this Blueberry Buckle recipe for some time now.  I finally decided that I was going to have to find an alternative, and boy, did I.  Wal-mart (my Grandma loved shopping, so I know she would have loved "my" Wal-mart - it's huge) has some great frozen fruits under their "Great Value" brand..and the blueberries, although frozen, when thawed are big and juicy.  This recipe card is a rather "catchy" one, it is one that is "professional" and I didn't have to try and figure out what the ingredients where or what to do with them once I figured it out.  But what I did decide to understand is where this cute card might have come from.  If you'll notice it has the name Red Farm Studio on the bottom of the card.  After doing a little research (Have I mentioned how much I like Google?), I found out that Red Farm Studio, makes greeting cards and coloring books...right up my dear Grandma's alley!!!  I suspect she ordered something from them for school and the recipe card was included..she neatly stapled it to a recipe card, and here we are.  Bubba loved the Buckle...that's all I need to say.
