How exciting - a crafty post!! I've actually made some cards! It's a miracle!
I bought some washi tape and wanted to try it out so cut a heart from the middle of a 6x6 Kraft card using spellbinders hearts nesting dies. I then cut the heart with the smaller die to make a smaller heart. I covered the smaller heart with stripes of the red and pink washi tape and stuck it in the middle of the heart shaped hole.
It doesn't give you a lot of space to write inside the card but I always struggle with what to write so that suits me fine!
I then drew a white dashed line on the front of the card to highlight it a bit
