What you need: A canvas in the size of your choice (I found mine on sale at Michael's), paint brushes (I already had on hand), and acrylic paint in your preferred colors. I chose a deep teal and a light moss green. I also got a slightly off-white color to fix edges and mistakes.
Find your font choice, I used "Tall, Dark, and Handsome" which I downloaded for free online. Print out the words/letters you want, cut, and trace onto the canvas. Then, just fill in the letters (or, paint all around the letters if you want a background color) with the acrylic paint.
