How to i.d. your fabric
When you can't tell if a fabric is a knit or woven, put it through these tests:
Look for loops or grain
In knit fabric (left), one continuous yarn is looped repeatedly to create what looks like tiny rows of braids. In woven fabric (right), multiple yarns cross each other at right angles to form the grain, like a basket.
Inspect the edges
A knit is either sold as a tube or flat. On flat knits, factories apply round blobs of starch or glue along the lengthwise edges to prevent them from curling. Along the width, or cut edge, the fabric doesn't fray. The lengthwise edges of a woven fabric, called the selvages, are strong and don't move. The cut edge across the width of the fabric frays.
