I have used recycled neckties (the silky, slinky ones) for hand applique by using some simple stabilizing techniques.  To make small circles (for grapes), I used the colored self-stick "dots" you can get at an office supply store.  Stick a circle over the area you want to use and cut about 1/4" around the circle.  You can cut shapes from any temporary self-stick (but not TOO sticky) material to hold the shape you want - pin down the seam allowance and use needle turn and tiny stitches to apply and then remove the stuck-on shape.
