Artwork clashing with your Christmas color-scheme? Not a problem - wrap it up! Like a present, that is!
This particular year I decorated in blue and silver and the existing artwork in my entryway just wasn't working for me. So...I came up with the idea of wrapping it to make it look like a Christmas present! Sorry to not have any how-to photos to include, but basically I just laid the artwork on top of my roll of wrapping paper and cut around each side leaving enough allowance to fold under. You don`t need to wrap the back, that part will be against the wall.
The same with the ribbon. I used Scotch tape, (not too much!) and it held just fine. I think I recall using a straight pin to attach the bow. Everything I already had on hand including the Dollar Tree `silver` trays. The sky is the limit with the options here.
