I also recently made this adorable baby subway art sign. I used my Cricut to cut out the letters from various carts. I then arranged them all on the canvas and mod podged the heck out of it. Do you see the silly numerical mistake I made? I didn't notice till we gave it to the new parents. So I took it back to fix it. Thank goodness the mod podge I used is not waterproof so I could scrape off the mistake!
