How to Sew a 1/4-Inch Straight Line

Your sewing machine should tell you where the 1/4-inch mark is.

Many sewing patterns require that you sew a 1/4-inch seam. Sewing a straight seam is important for clothing or craft items to fit correctly, so learning how to sew a straight 1/4-inch seam before beginning your sewing project is a good idea.

Things You'll Need

• Sewing machine
• Measuring tape
• Fabric
• Thread

Instructions

1. Examine your sewing machine. There should be hash marks on the plate under the needle. The hash marks are to the right of the needle. Find the 1/4-inch mark; this means that from the needle to the mark is 1/4 inch. If your marks aren't labeled, hold your measuring tape under the needle to find 1/4 inch. Mark the width with a straight line of masking tape or other marker.

2. Thread your machine with the thread of your choice. When doing most sewing crafts, use a thread that blends in with the fabric.

3. Put your fabric under the needle; the edge of the fabric should be to the right of the needle.

4. Line the edge up with the 1/4-inch mark. Slowly press the sewing machine foot pedal to get the needle started.

5. Guide the fabric under the needle, always keeping the edge of the fabric along the 1/4-inch mark.

Tips & Warnings

• Sew slowly to keep the fabric under control. As you get more experienced, you will be able to go faster.
