Second Year Students-Competency 3 Review

When constructing a pair of slacks, the crotch length should be comfortable when sitting or bending.

A Universal sewing machine needle is sharp enough to pierce tightly woven fabrics yet rounded enough to push aside the yarns of a knitted fabric without leaving holes.

When constructing a set-in sleeve, the armhole measurement is slightly smaller than the sleeve. Easing is the sewing technique used to put in a smooth seam.

Hook and loop tape is an appropriate closure for a person with limited hand use.

If a flap will not lay flat when buttoned, correct the problem by realigning the button

When constructing a garment, select interfacing that is similar in weight to the fabric.

In manufactured garments, the usual seam allowance is a minimum of 1/2".

When switching from a medium weight cotton blend fabric to a faux leather while sewing, the needle type should be changed.

On a conventional sewing machine, the pressure regulator adjusts the amount of pressure applied to the presser foot.

A blind stitch presser foot is appropriate for constructing an invisible machine-worked hem, especially on top finished edges of a canvas bag.

To allow leather to feed smoothly while sewing on a conventional sewing machine, change the presser foot to a Teflon or walking foot.

To keep seams from feeding unevenly when joining two heavy weight fabrics, increase stitch length.

Decrease the pressure regulator on the serger when serging a lightweight cotton fabric.

Use general purpose thread for the overlock stitches when constructing a cotton fabric tissue holder using the serger.

A point presser is the pressing tool with a narrow wooden surface with a triangle shape end that is used to press sharp edges.

A zigzag seam finish using a medium width and stitch is a fast and easy seam finish for upholstery fabric.

The blind stitch sewn by hand can be used to incorporate an invisible hem and control excessive fullness in the hem, especially when constructing a valance.

When the hem of a linen skirt is turned up 1/4", then turned again 1 1/2", the hand stitch used to hem is the blind stitch.

Product styling and material should be considered FIRST when choosing a closure based on the appearance within a design product.

Heavy-duty hooks and bars are the most appropriate closure for waistbands.

The most appropriate hem finish for heavyweight fabric that ravels easily is the bound hem finish.

Clip an underarm seam to ensure that the seam curves correctly.

When pinning down a pattern, use the correct pattern layout to make sure that the pattern pieces are cut on-grain.

Unevenly spaced buttonholes are NOT a sign of quality apparel construction. Buttonholes that are firmly stitched with reinforced corners that lie smooth and flat are much better quality.

Interfacing helps create a smooth crisp collar during garment construction.

Serging is the LEAST suitable method for finishing the bottom of a sleeve. Better options are casings, cuffs, and hems.

A serged seam finish is appropriate for a dress made from lightweight knit fabric.

To reduce bulk in an enclosed seam and ensure a quality product, grading the seams is the best technique.

The best way to reduce bulk around the neckline in a coat made from heavy fabric is to grade the seam.

In a quality made garment, the facings should have finished edges, lie flat against the body, and turn to the inside of the garment. The facings should NOT be visible from the outside.

Snaps are appropriate fasteners for children's sleepwear.

Signs of a well fitted garment are: a collar that lies close to the neck, pleats that hang vertically, zippers that open smoothly. Uneven hems are NOT a sign of good fit.

A buttoned cuff should fit comfortably around the wrist.

When analyzing garment fit, be sure that chest and back fit smoothly. Armholes that restrict body movement, a crotch area that wrinkles and binds, or a binding waistband are NOT good fit.

POOR garment fit is indicated by hemlines that are not parallel to the floor. GOOD garment fit is indicated by buttons that do not pull or strain, pants legs that fall straight from the hipline without wrinkles, and a waistline that does not bind. Sleeves should cover the wrist bone with the arm bent. Collars should fit close to the neck.

Well-made hems have a flat and smooth hem edge, stitching that does not show on the outside, and the garment hangs evenly around the body. Poorly made hems have the edges slightly longer in the back or front.

Quality workmanship in garment construction includes: even stitching, smooth seams, straight hems. Plaids should match, collars should have smooth curves and seams should be straight and even. Darts should NOT have a dimple at the point. Buttons should be the right size for the buttonhole, fabrics (especially loosely woven ones) should have seam finishes, thread color should match the fabric. Facings should lie flat against the body, trims should be sewn securely, zippers should open and close easily.

The serger can make a flatlock decorative seam and trim edges while sewing.

No serger adjustment is needed to serge a satin pillow sham.

The serger is an industry machine that will trim the seam as it sews.

For a cushion manufacturer to cut 100 stacked layers of fabric by hand, an electric stright-knife cutting machine would be used.

The rotary cutter works best when cutting rectangular and straight markers.

Use embroidery scissors to clip threads from work in a machine-embroidery hoop.

Seams on corduroy should be pressed open using a steam iron, needle board, and pressing cloth.

A steam iron is used to press conventional seams.

Welt seams are a decorative seam suitable for a tailored bag of heavy weight corduroy.

The French seam is appropriate for constructing an heirloom bag of cotton batiste.

Use a lapped seam to sew together pieces of leather for a bag.

A zigzag or serged seam finish is good for heavy fabrics that ravel.

Serged seam finishes are good for canvas window treatments.

A clean seam finish is made by turning and stitching the seam allowance 1/4" from the edge to prevent raveling.

A French seam can be described as a seam within a seam. It is very appropriate for an unlined satin jacket.

The piped seam is constructed by incorporating cording within the seam. It is often used when constructing decorative pillows.

Quality workmanship in collar construction includes: both sides of the collar being identical, curves are smooth, points are sharp and even, the collar circles the neck smoothly without ripples, the collar covers the neck seam in the back. The undercollar should NOT show along the edge, and the interfacing should NOT be heavier than the fabric.

Raw edges of apparel should be covered with appropriate hems.

Before purchasing an apparel item made with napped fabric, the consumer should make sure the nap runs in the same direction.

A shirt tail hem is good to use on medium or heavyweight fabrics that ravel a great deal.

Use a slip stitch for hems with a turned and stitched finish or a bias binding finish.

Hook and loop tape used as a closure on a bag of hard-to-match print fabric is not immediately obvious.

Snaps are an appropriate closure for overlapping edges that receive a minimum of strain.

Snaps are a good closure to use on a terry-cloth cover-up.

When applying hook and loop closure to a bag, apply the loop side to the overlapping part. It is less likely to snag when applied this way.

To sew with metallic thread, the machine needs a special needle.

Garments should be made with wearing ease to fit properly.

Collars should circle the neck without rippling.

A quality indicator for a set-in sleeve is fullness ease without puckering.

Unfinished seams and hems are signs of poor workmanship.

When evaluating a garment's fit, bend and touch toes, raise the arms over the head and sit down to check for pulling.

The self-enclosed seam usually found on jeans is the flat felled seam.
