There are so many ways to change and enhance clothing. One that I love for kids clothes is a simple machine applique. You can use pinking shears for the raw edge to cut down on fraying. Or you can use regular scissors for a raw edge. I really like the effect the pinked edges give it. You can cut out a part of the printed design on the fabric or create your own design. I use some temporary spray adhesive to hold it in place (pins move so much...they could work but spray seems to work best for me). Sew around it with a straight stitch and viola! Cuteness.
So if you have a plain tee that needs something extra, try a machine applique.
Next... machine applique with a satin stitch. Stay tuned!
