I have a nephew turning 10 in January this year and wanted to make a boyish looking card for him but not have it be too childish looking. After looking on Pinterest for ideas, I found these cards:
Since I don't have the stamps used on either of these cards, I made an svg cut file for my Cricut and cut out the jets and blue angels in black then used these lady's ideas for the white smoke on the card.
I used my all time favorite Happy Birthday die from Frantic Stamper on the blue angels card.
For the white smoke, I just took a finger ink dauber with just a small amount of white acrylic paint, dragged the dauber along in a line. For the heart smoke, I masked off the area with a punched out heart first then ran the white paint on the dauber all around it.
