Sewing a poncho without a pattern involves measuring the wearer and making a couple of cuts in a square of fabric. This method works for children and adults, and it takes about an hour. You need fabric, a measuring tape, scissors, a small plate, thread and a sewing machine or hand-stitching needles.Continue Reading
Have the intended wearer extend her arms straight out from her sides. While the arms are extended, spread the measuring tape across the back, and measure the distance from one wrist to the other. Add 1 inch to this measurement.
Select a fabric that is sturdy enough for outerwear and that drapes enough to be comfortable. Take into account the appearance the fabric's underside, which may be visible. Cut a square of fabric using the measurement obtained in the first step.
Fold the square in half, and then fold it in half again. Choose a small plate, such as one used for salad or dessert. Place the plate on the fabric square's folded point, and cut a semi-circle using the plate as a guideline. Remove the plate, and slide the scissors into the fold, pointing from the semi-circle down to the edge. Make a small slit of 3 to 6 inches. This provides a small opening in the front of the poncho.
Turn all raw edges under 1/4 inch, and sew with a machine or hand needle. Turn the edges under another 1/4 inch, and sew again for a finished edge that prevents fraying.
