Whatever is decided it should first be sketched on paper. Felt is a terrific fabric for this project as it doesn't fray. A pumpkin, for example, can be drawn and used as a pattern. Once it is cut out it can be stitched by hand onto the bag. Ribbons and scraps of material can likewise be included.
Buttons make good eyes and small stencils can be used with fabric paint.
Fabric paint is a very good craft supply to use for this project. The fine painting point is excellent to decorate the bag's handle and side. Don't forget there are 2 sides to the bag. Make sure that the first side of your bag is completely dry, if using paint or glue, before decorating the other side of the bag.
