iron, using a dry iron. Allow hessian to cool: STEP FIVE Cut out the fabric transfer and place it face-up on the hessian (you can trim closer to the image if you wish; not really important on hessian, but looks better on fine fabrics): Faff about with positioning until your happy, then flip it over, so that it's face-down on the hessian: Using a very hot iron, (with no steam), press down firmly on the transfer for 4 or 5 seconds, keeping the iron still. Lift the iron clean off for 5 seconds and repeat the hot pressing process three or four more times, paying particular attention to areas with dense ink. You will find that thin, smooth fabrics require less pressing time than thick, course textured fabrics, such as the hessian we're using for this: STEP SIX Very slowly, peel away one small edge of the transfer. If the backing paper comes away easily (and without much ink on it), continue peeling. If the transfer paper is sticking, continue the hot pressing: STEP SEVEN Leaving a one inch margin, with the good sides on the outside, pin, then sew the two pieces of hessian together: You can hand sew if you wish, but I used a zig zig machine stitch in red to add a little contrast, and to help stop unwanted fraying. Leave a small section un-sewn. Fill your sachet with Christmas pot pourri or lavender and stitch the gap:
