As a hostess gift for a Christmas Eve dinner I was attending I made this simple flower arrangement. 
To begin, I bought green pom pom mums and a bag of cranberries at the grocery store. I wrapped a wide piece of coordinating green ribbon around a narrow glass vase, tucking under the end and using a glue gun to secure it. I then added a red ribbon over top which I tied into a bow in the front.
After trimming the mums down to the desired length I arranged them in the vase. To add some extra color to the arrangement I then carefully added cranberries around the stems of the mums.
The arrangement turned out to be bright and festive and since I could make it with items from the grocery store and ribbons I had on hand it was easy and inexpensive as well.
