When you're hemming fabric -- whether for table linens, curtains, or clothes -- accuracy is important. Ensure good results and save time with this technique: To make a 1-inch hem, for example, draw a line on card stock, 1 inch in from an edge. Place the card stock on fabric, with line parallel to fabric edge. Fold fabric over card stock, aligning fabric edge with line; press with an iron. Repeat, folding and pressing again to encase the raw edge. Stitch hem to secure.
