NEVER put your sweater in a dryer!
Roll the wet garment in a dry towel and twist both ends of the towel to remove excess water. Lay flat on a 2nd towel and allow to dry naturally .
Keep away from any direct source of heat such as radiators or sunlight.
Once dry, press to shape carefully using a medium-setting iron and with a damp cloth on the garment to prevent over-heating and damaging the fibers.
