This pack from DMC contains 4 sheets measuring 21.5 x 28 cm of wax-free transfer paper.
 
There are two pale yellow sheets for use on dark fabrics and two of pale blue for light fabrics. 
 
It works by placing a sheet coloured side down, onto your fabric. Then draw on the transfer paper any design that you want, pressing firmly. The design will then be transferred to the fabric enabling you to easily stitch your design along the lines.
 
Most of the markings will be covered by your stitching but any remaining marks can be removed by a damp cloth.
