IRON ON TRANSFERS
You do not need to trace your own outline, you can purchase an iron on transfer for each project in the embroidery shop. These are simple to use and provide a nice clear outline on your fabric. If you prefer to trace your own outline or do not have access to transfers here is the method.
HOW TO MANUALLY TRACE AN OUTLINE
Place pattern outline on a light source such as a window or lightbox. Tape in place. Center fabric on top of this, tape in place with masking tape/similar to secure. Using an HB pencil or fine micron pen trace over the the outline.
