WHITE 1510 (01) PDF SUMMARY:

What are some good habits to follow each time you sit down to sew?

1. Test the needle: it should be straight, properly set and sharp on the point. It should be the correct size for the fabric and thread being used. Do not be afraid to change your needle frequently. Many of the new fabrics made of synthetic blends tend to dull the needles more easily than fabrics made of natural fibers.
2. Before placing the material on the machine, see that the ends of the threads have been drawn about 6 inches to the rear of the machine. Hold on to threads during the sewing of the first 3 or 4 stitches of the seam.
3. Test the machine stitch on a scrap of fabric you plan to use. The fabric should be double thickness. Adjust the machine for the length of stitch and tension suitable to your fabric.
4. Fabric should be placed under the presser foot with the bulk of the material to the left of the needle and the right edge of the material placed on the appropriate seam marking for desired seam edge.
5. Run the machine at a slow even speed. The more pressure you put on the foot control, the faster the machine will sew.
6. Fasten each seam by back tacking at the beginning and end of the seam.
7. Always finish sewing each seam with the needle at its highest point.
8. Guide the fabric gently with your hand in front of the needle. Never pull or hold the fabric in such a way that the normal feeding is altered.
9. When turning the hand wheel manually, always turn it toward you.

How do you turn a square corner?

To turn a square corner 5/8" from the fabric edge, stop stitching with the needle tip piercing the fabric, when reaching the cornering guide as shown, Raise the presser foot, turn fabric. New stitching line will align with 5/8" seam guide on side of needle plate. Lower the presser foot and begin stitching in new direction.

---

How do you adjust thread tension?

Test stitch performance on a scrap of material you are going to use. With correct tension (a), upper and lower threads tension is equal and strong enough to lock both threads in center. If upper tension is too tight (loose), upper (lower) thread lies straight along upper (lower) surface of fabric (b.). Correct by turning tension dial.

---

How do you set the machine for straight sewing?

Set machine as shown. 3 kinds of straight stitch lengths can be selected as shown below.

---

What are the stitch length options for straight sewing?

Stitch Selector	Stitch length
No. 5	2mm
No. 6	3mm
No. 7	4mm

---

How do you set the machine for zigzag sewing?

Set machine as shown. To prevent seam ends unravelling, set machine for straight stitch and sew in reverse at beginning and ending of seam.

---

What adjustments do you make for thread tension for zigzag stitch?

Better-looking zigzag stitching requires less upper tension than straight stitching. Loosen upper tension slightly.

---

How do you determine the length of a buttonhole?

Measure diameter and thickness of button and add 0.3cm (1/8") for bar tacks. Mark buttonhole size on material.

---

How do you attach the buttonhole foot?

Completely push back sliding part a of buttonhole foot. Place material under foot so that marking of buttonhole passes through center of foot and arrow b of foot indicates beginning line of marking.

---

How do you create the bar tacking?

Set pattern selection dial to 1 and sew 5-6 stitches.

---

How do you sew the left side of the buttonhole?

Change pattern to 2. Sew left side from front to back until it reaches end line. Remember the point where arrow shows so that it is not necessary to mark end lines for all buttonholes.

---

How do you create the bar tacking on the other side?

Change pattern to 3 and sew 5-6 stitches.

---

How do you sew the right side of the buttonhole?

Change pattern to 4 and sew right side until it catches first bar tack.

---

How do you adjust the stitch density on the right and left sides of the buttonhole?

Stitch density on right and left sides of buttonhole can be adjust by buttonhole balance control dial. This dial should usually be in a neutral position (between “+” and “-”). If the stitches on the right side of the buttonhole are too close together, turn the dial to the right (+). Turning dial to right opens right side and closes left side. If the stitches on the right side of the buttonhole are too open, turn the dial to the left (-). Turning dial to left closes right side and opens left side.

---

How do you cut buttonholes?

Stick a needle through bar tacks to prevent over-cutting. Cut buttonhole along center with buttonhole cutter.

---

How do you create corded buttonholes?

For stretch fabrics such as knits, a corded buttonhole is effective to keep finished buttonhole in shape. Hook filler cord on top spur and lead ends of cord under foot, pull taut, and hook them to bottom notches as shown. Proceed with stitching as for regular buttonholes. When buttonhole is completed, pull filler cord ends so that loop on the other end disappears into buttonhole stitching. Thread ends of cord to reverse side and tie, or cut both ends of cord.

---

---

How do you adjust the stretch stitch balance?

In stretch stitch sewing, the stretch stitch adjuster should usually be in a neutral position (between “+” and “-”). When sewing some fabrics, you may need to adjust this control to balance the stitches for appearance sake. If design seems open adjust the control slightly toward “-” until design looks like the center design. If the design appears to be closed, turn the control toward "+"until stitching is as you desire.

How do you sew straight stretch stitching?

Use this stretch stitch with knitted fabric and other fabrics that stretch. Sew as you do with regular straight stitch seaming. The seam may be pressed open as with any regular seam, but will stretch if necessary. This is also a good stitch to use on curved seams regardless of the type of fabric. Any seam that will receive a great deal of strain when worn should be sewn with the stretch stitch. Use in children’s shorts and slacks as well as adult sports clothes.
