First Year Students-Competency 3 Review

To prevent injuries while sewing the machine operator should sit up straight and keep fingers away from the presser foot.

If the needle and bobbin threads have the proper amount of tension, the stitches will be identical on both fabric front and back.

If the pattern selector dial is set for a zigzag stitch and the machine continues to sew a straight stitch, you need to adjust the stitch width.

Broken threads on the serger usually occur when looper threads are crossed.

A four-thread serger cuts seam allowances off and overcasts the seam edge.

To chain off with the serger, serge off the fabric, bring the chain and fabric around so the chain crosses in front of the knife.

On the sewing machine, the stitch length regulator determines the length of the stitch.

The feed is the part of the sewing machine that moves the fabric under the presser foot.

The presser foot holds the fabric in place during stitching.

The stitch width regulator is the part of the sewing machine that regulates the width of zigzag stitches.

The sewing machine needle is held in place by the needle clamp.

To operate the sewing machine, press down on the foot/knee control.

The owner's manual is the BEST source of information about the use and care of the sewing machine.

The bobbin winder is the part of the sewing machine that allows the operator to fill the bobbin with thread.

The needle clamp screw of a sewing machine should be tight to prevent the needle from falling out.

The needle plate/throat plate has the guides for seam allowances.

The bobbin is the part of the sewing machine that forms the lower part of the stitch.

The tension control is the part of the sewing machine that controls the tightness of the upper thread.

On the serger, the needles work with the loopers to form stitches.

Knives are found on the serger but not on the sewing machine.

The hand wheel raises and lowers the needle on both the serger and the sewing machine.

The serger function that cannot be done with a sewing machine is to trim, stitch, and overcast in one step.

Loopers on the serger compare to the bobbin on a sewing machine.

Incorrect threading of the machine can cause the thread to break while sewing.

When first learning to sew, the machine operator should use a slow speed.

The FIRST step to clean the sewing machine is to turn it off and unplug it.

The FIRST thing to do when the sewing machine will not stitch is to check the threading.

The type of fabric determines what type of needle to use in a sewing machine.

To check the threading of the sewing machine before beginning to sew, run a test sample on a fabric scrap.

The best method to secure the end of a serged seam is to use seam sealant.

The operation that completes the end of a serged seam is to chain off.

The serger problem indicated by jagged fabric edges is dull knives.

If a person sews over pins while serging, it may damage the inner workings of the machine.

When serged stitches are not smooth and even, check to be sure the presser foot is lowered.

The serger part that is always threaded LAST is the needles.

Serged stitches can easily be removed with a seam ripper.

One step in completing a serged seam is to press the seam to one side.
