Piano card for my grand daughter

We went out of town last week to see our oldest grand daughter's first piano recital.  She just started piano lessons in the fall and her teacher felt she had improved enough to participate!!  I wanted to let her know that we were proud of her and "good on her" for doing well with her piece. 
So I decided to make a musical card for her and I found this piano card  tutorial on line which seemed pretty straight forward so I decided to give it a go.  I started with a black card base.  I cut a piece of white cardstock and added black lines with a permanent marker.  I used this method of marking even spaces on a piece of paper using a ruler and it worked perfectly to define the white piano keys.  I found some small scraps of black cardstock and cut them about 2/3 of the white piece and used double sided tape to glue them over the lines.  I was sure to put them in the correct order by finding a piano on line and duplicating the pattern.  I hand drew the grand piano shape and trimmed it with scissors.  I printed the sheet music offered in the tutorial and glued it to the inside of the card.  I added a small insert on the inside front of the card to write my note!!  Very happy with how it turned out!!
