This method is also known as Raw edge Appliqué. In this method top fabric is fused to the base fabric. A fusible web binds both the top and base fabric by ironing. once the design is traced on the fusible web, cut it to the exact shape, iron it on to the chosen fabric and feel off the backing paper exposing the glue, iron it on to the base fabric.
My favorite brand of fusible web is Heat N Bond available in quilt shops. This has a paper backing and easy to use.You can also buy the fusible web in roles without paper backing or in meters. The ones without backing can be used by placing them in between baking parchment. If you cannot get this webbing you can use a fabric glue or glue stick which may not be perfect but can work. A special iron is another added tool but normal iron can do the same task.
Chose a design.
Cut out the shapes from the traced design on fusible web and iron it on to the back side of the selected fabric. Cut out all the fused shapes with one side exact and other side a scant 1/4 inch eye measurement. The idea is to fit each piece like jigsaw puzzle.
Stitch around all the edges with straight stitch. If you don’t like the raw edge look you can statin stitch around the edges.Once the process of fusing and stitching is finished thread painting it with matching thread is an option
