Here are the commonly used names for the basic shirtings:
- Hairline Stripe
- Dress Stripe
- Pin Stripes
- Candy Stripe
- Bengal Stripes
- Awning Stripe
- Shadow Stripe
Candy Stripes approximately 1/8" equally spaced white & colour or colour & colour;
Bengal Stripes +/- 1/4" equally spaced white & colour or colour & colour, etc.
Pin stripes are usually 1 or two yarns thick and the spacing between pin stripes varies all over the map.
If you'd rather call your Candy Stripes Bengals and your Bengals Pinstripes, feel free. One person's tiger is another's kitty.
