I took a 6x6 blank white canvas, and made a homemade heart template by folding a 5x5 white square and shaping it into a heart. Using the negative of that paper, I ventered the template over the canvas and began using red buttons and glue dots to secure them.
I worked from the bottom up, and did the edges first.
I took red gingham ribbon and glued it to the edges of the canvas for a finished look, and that was it!
Enjoy your day!
