Print out the word "hello" onto copy paper.
Take your fabric, making sure it's wrinkle-free, and put it on top of the printed copy paper. Hold both up against light so that you can trace the word "hello" with your pencil onto the fabric.
Take your paintbrush and paint and paint in the word on the fabric, staying in between the lines. Use two coats if needed, and you can also use a small brush to clean up the edges with a little additional paint.
Get started on your leaves while your paint dries. Use a drop of hot glue in the center of one end of the leaves and pinch together. Use clothespins to hold the leaves while the glue dries so that your hands are free.
Once the hello word art is dry, put it into your embroidery hoop and stretch it tight. Then flip around to the back and use a craft knife to trim the fabric as close as you can to the edge of your embroidery hoop.
Start using hot glue to layer on as many of those leaves as you would like around the edges.
