For light colored fabrics:
One of the easiest method to transfer your designs from paper to fabric is to use light. Tape your design to a sunny window and place your fabric over it. With the light shining through, you will be able to see the design clearing through the fabric. Trace the pattern directly onto the fabric using a pencil or water soluble transfer pen.
For dark colored fabrics:
Use a light colored piece of carbon paper to transfer your designs on darker fabrics. To do so, place the carbon paper color-side down on your fabric followed by your pattern on top. Use a pencil or ball point pen to trace your pattern, ensuring that all three layers do not shift. Be careful not to lean your hands on the carbon paper while tracing as this can cause stains on your fabrics.
