Appliqué using the freezer paper & glue stick method is a great way to achieve smooth curves and complex shapes.

You'll need Freezer Paper, scissors, glue stick, a pencil, a pattern or template, fabric, an iron and needle & thread.

Trace your pattern onto the dull side of the Freezer Paper. Cut out on the drawn line. Place the shiny side of the freezer paper onto the wrong side of the fabric and press with a hot, dry iron.

Cut out the fabric leaving a 1/4" seam allowance all the way around the freezer paper.

Rub the glue stick close to the edge of the seam allowance, a little bit of fabric at a time. Using your fingers fold the fabric over the edge of the freezer paper, work your way around the shape (clip around all curves to ease the fold )

Pin or lightly glue your shape to the background fabric. Appliqué the shape to the background using a straw needle and matching thread.
