Step 1: Select material. You want something suitably stretchy and lightweight. Microfleece or t-shirt weight knit are good choices. I used a lightweight polypropylene, which is extremely warm and wicks moisture away from the skin. You will only need about 25cm for an adult hat, and less than 20cm for a child’s hat.
Step 2: Wrap around head and pin. It wants to be fairly loose, but not so loose it’s going to bag or be bulky in the hat:
Step 4: Put lining back on head and pin across top of head, leaving the lining a good 5cms longer than it needs to be (turn it up and pin so its out of your model’s eyes!).
Step 7: Over lock bottom seam, and pin to desired length (place your pins on the right side – this will be the inside of your hat)
Step 8: With seams facing outwards pin lining evenly into hat… check you cant see any seams at this point!
