Polyester can come in different weights, can be used for a wide variety of garments, it is hard wearing and does not lose its shape, it will fray so would benefit from overlocking or zig zag stitch the edges. Tip ...when pressing place a folded piece of paper between the seam and the main fabric to prevent indentation of the stitches showing through, (especially if you have used an overlocker) onto the surface of the main fabric. Use a pressing cloth, preferable silk organza, as with all polyester fabrics they do burn easily if the iron is not on the correct setting but will also "shine" if too warm iron is used. Machine wash on a warm , not hot, wash and avoid overdrying in the tumble dryer as it can cause the fibres to become very static, so always use an antistatic lining.
Sew using a microtex needle 60 or 70 with a stitch length of 2-2.5mm, preferably sewing a french seam. For interfacing use silk organza or G785 which is soft lightweight iron-on woven interfacing. Press using a cloth, a silk organza cloth is your best friend with this type of fabric.
All polyesters are machine washable on a warm wash and do not over dry in a tumble dryer, would be better to air dry to prevent static build up, iron on a cooler setting.
