I cut out the state I wanted from a U.S. road map. Cut a piece of fabric a little larger than the state.
Iron on a piece of Heat n Bond to the back side of the fabric.
I put my state face down on the heat bond and traced around with a pencil.
Cut out state with fabric scissors, peel off heat n bond backing paper and iron on to a onesie.
Add a star for the city if you desire the same way you did the state.
Easy peasy! A no-sew baby shower gift!
