All of the following characteristics are true of cotton EXCEPT: • Strong and Durable • Absorbent • Wrinkle resistant • Accepts dyes and prints easily
Blends are created: • To utilize the positive characteristics of each fiber • To reduce the cost • So the fabric will be washable • By using three or more fibers

Stains may be permanently set by: • Placing the stain in cold water immediately • Leaving the stain untreated for too long • Heat of any kind • 2 and 3
To remove blood stains from washable fabric: • Soak it in cold water • Wash it in hot water • Pour bleach directly on it • Use a non-enzyme detergent
To remove ink: • Soak it in cold water and then rub with detergent • Sponge with white vinegar and rinse • Spray lightly with hair spray or sponge with rubbing alcohol • Pour bleach directly onto the stain
Allowances made by pattern companies for fit is: • Extensions • Seam Allowance • Grading • Ease
Symbols including grainline, notches, buttons and buttonholes are found on the: • Pattern envelope • Pattern guide sheet • Pattern pieces • Pattern Book
Pattern layout options are found on the : • Pattern envelope • Pattern Guide sheet • Pattern Pieces • Pattern Book
The pattern symbol illustrated below is: • The grainline • A notch • The line to shorten or lengthen • The stitching line
A broken or dashed line on a pattern is the marking for: • Straight of grain • Buttonholes • Placing the pattern on the fold • A stitching line
A solid arrow line that is bent on both ends is the pattern marking for: • Placing the pattern on the fold • A stitching line • A dart • The shortening or lengthening line
Small diamond/triangular shaped markings on pattern pieces are: • Directional sewing lines • Notches that are used for matching pattern pieces • Pattern decorations • Used for shortening or lenghtening
The pattern symbol illustrated at the bottom is: • The stitching line • A Dart • Directional sewing lines • The cutting line
On one size patterns the heavy solid line on the pattern indicates the: • Basting line • Seam Allowance • Cutting line • Notch line
The purpose of topstitching is to: • Improve/enhance the appearance and add durability • Finish Edges • Prevent the edges from stretching • Prevent the edges from raveling
The purpose of clean finishing is to: • Maintain the grainline • Prevent raveling/fraying • Prevent stretching • Improve/enhance the appearance
Grading/layering is: • A small cut into the seam allowance almost to the stitching line • The cut edge of the fabric pieces • Trimming each layer of a seam allowance in varying amounts to reduce bulk • An extra thickness of fabric used to provide shape
The fabric outside the stitching line is: • The seam allowance • Extra fabric • The selvage • Clean finished
The diagonal angle to the grain of the fabric is the: • Selvage • Lengthwise grain • Crosswise grain • Bias
A small short cut made in the seam allowance of a curved seam, to help the seam lay flat is: • Grading/layering • Trimming • Clipping • Basting
The lengthwise and crosswise direction of the fabric is the • Balance • Ease • Line • Grain
Stitching placed 1/8” or less from the edge is: • Topstitching • Edgestitching • Grading/layering • Understitching
The threads running parallel to the selvage are the: • Crosswise grain • Lengthwise grain • Selvage • Bias
The threads running perpendicular to the selvage are: • Bias • Lengthwise grain • Warp • Crosswise grain
Stitching done through a single thickness of fabric, to add stability and prevent stretching during construction: • Understitching • Grading • Backstitching • Staystitching
The tightly woven finished edge of the fabric is the: • Bias • Lengthwise Grain • Crosswise Grain • Selvage
The pattern symbol illustrated at the bottom is: • A dart • A tuck/pleat • The fold line marking • The button/ buttonhole
The standard seam allowance for a woven fabric is: • ¼ inch • ½ inch • 3/8 inch • 5/8 inch
One-way or directional fabric means that the: • Fabric must be sewn in the same direction • Lengthwise threads are parallel to the selvage • The tops of the pattern pieces must always be the same direction • The pattern will use less fabric than a two-way directional fabric
Which is usually the FIRST step in preparing a washable fabric for sewing: • Preshrinking • Cutting • Pattern Layout • Straightening the grain
When preshrinking a washable fabric it is important to: • Wash and dry the fabric the same way it will be laundered • Wash in hot water and dry completely in the dryer • Wash in cold water and line dry • Wash the fabric the same way it will be laundered, then line dry.
