I have avaliable my Christmas music card set. This set is more of a vintage colored background. They are printed on different Christmas songs.  They are avaliable in note cards and greeting cards. 
The note cards are 4x6 and come with envelopes.  You will receive 2 of each card.  The greeting cards are 4x6 mounted to a 5x7 cards stock and come with envelopes.  In the drop down you can choose the amounts and size you'd like.The images on the sheet music are prints of my original watercolor paintings.
