Here’s a tutorial for how I made this card.
I drew the piano shape by hand and cut it out with a pair of scissors on the open side. (You can use a rotary cutter to cut several of these at a time if you’d like.)
I then cut off 1.75cim from the front panel of the card only. On the inside part that became exposed, I added the keyboard. (When I made this card I simply googled a keyboard but I have since created my own keyboard in Photoshop).
In order to add the ribbon across, I cut another strip of the red cardstock, attached the ribbon to that, then added it to the bottom of the front panel. I tied the bow onto that piece of ribbon.
The next step was decorating the top. You can do this any way you like. I liked how the same colour medallion looked. Here are the dimensions. It was a little bit wider than my usual 5 x 7 cards.
ps: If you make this card, I sure would be happy if I could see your version of it. Send me a link if you don’t mind.
