Choose a piece of fabric in the base color of the flag you wish to make. If you're making an American flag, for example, you can stick with plain white. To make a large flag, try to use a piece of fabric measuring 5 foot (1.5 m) by 3 foot (0.9 m). If you want a smaller flag, a smaller piece of fabric (or even a pillowcase) will do. It doesn't matter what type of fabric these pieces are, they can be nylon or cotton like the flag, or they can be felt, silk, polyester, velour - whatever you can find around the house! Pieces of old clothing, or old tablecloths are perfect for this. For a DIY flag, the flag handle can be made from whatever you choose - it could be a tree branch or an old broom pole  - as long as it's strong enough and long enough to hold your flag.
