Refurbishing Store Bought Cards - Christmas

This a sample of the store bought Christmas cards in my stash accumulated over many years.  I am working to refurbishing these into useful cards.  I find store bought cards a challenge because they are generally larger than the A2 invitation size I normally make, so the images are sometimes too large.  At times, I can trim them to fit on the smaller card bases.  The smaller cards work at lot better like the We Wish You a Merry Christmas.  See the sample below.

Here's a few cards I made from the stash above. 
The tree was trimmed very close and mounted onto red card base. 
The Joy was a small card which I trimmed then mounted onto a white layer then onto a matching blue card base.
The star had wonderful color so I chose a deep red burgundy card base to which I adhered the trimmed store bough card.  Then I added the greeting made from gold Stampin Up Decorative Label punch, a green label and the greeting is a SU Word Window punchie.
The We Wish You card as a small one trimmed then adhered to a kraft layer to which I added a black hand drawn border to repeat the black in the store bought card.  It was adhered to a warm red card base.
The Peace earth was a small card, trimmed to the right proportions then adhered to a deep red card stock then adhered to a matching blue card base.
The winter street scene was trimmed a lot to get it to the right size the adhered to a mint green card base.  I added 3 white tiny star brads in the center of the glitter snowflakes in the top of the Thomas Kincade image.
The triangle tree with words was a small card, trimmed and layered to a gold spattered brown layer which was then layered onto a bright green card base.

Check your place for old Christmas cards and see how you might re-use pieces to make your Christmas cards this year.  A green idea which re-uses and saves paper and ultimately trees.
