Some tidbits of info -
Thread passes through the needle eye in an up and down motion very quickly before it forms one stitch. To achieve a perfect stitch, you need three things:
correct thread - correct size needle - properly adjusted tension
Choose thread that is compatible with your fabric. Always choose a good, high-quality thread that won’t split easily. Using a low quality thread creates excessive lint build-up, and has frayed edges and roughness in the thread. Hold your thread up to a good light. Does it look nice and smooth, or frayed and rough?
Next, select the proper needle to match the fabric. Choose the needle type (i.e. jeans, microtex) and the needle size to match the thread. Is it hard to thread your needle? Then needle size may be too small for the thread.
Always start with a new needle!
- Numbers on thread spools need not be confusing. The first number (i.e. 40/3, 100/3) is the size of the thread. The second number is the number of plys of the thread when twisted together. The more plys, the stronger the thread. A general rule is 2 ply for decorative stitching and 3 ply for machine stitching. Remember, thread quality and strength has evolved so much over the years you may want to try many types!
- The higher the number, the finer the thread. The medium size is 40 - 50 wt. Thread sizes range up to 100.
- When selecting silk thread, 100 weight is the best. It is the smallest size offered and can match any fabric. Also available in 30 wt, and 50 wt.
- When letters indicate size, A is fine and D is heavy.
- What color of thread to use? Select one shade darker than the fabric. If the fabric is multi-color or plaid, choose the most dominant color.
- Thread does deteriorate over time. Store with care away from extreme moisture or dryness. Store in a covered container to keep free from dust.
Some thread types -
Strong and has a bit of stretch. Smooth and free of ‘fuzzies”. Blends into seams, almost invisibly and keeps a free-flowing seam. Silk thread is perfect for basting since it doesn’t leave an impression on the fabric. Silk takes on the color of the fabric, so a huge color assortment is not necessary. Perfect for sewing all fabrics, but excellent at sewing silks and woolens. Does the best job for sewing rolled hems with a tighter edge.
Cotton Wrapped Polyester
Combines the strength of polyester core with cotton wrap, smooth seams with a natural give and works well on cotton knits.
100% polyester provides strength and flexibility for sewing on knits, stretch fabrics due to its stretch and non-shrinkage. Also use to sew on any natural fabrics, those with blended fibers, and synthetic.
Smooth finish, good shine.
100% cotton thread.
Perle (pearl) cotton thread
A 2 ply, hi-sheen, non-divisible twisted thread (why sometimes referred to as one strand) and used in many forms of needlework. Oftentimes used in the bobbin only.
Heavy duty is abrasion resistant and does not deteriorate so can be used both indoors and outdoors. Perfect for upholstery and heavy duty home decorating projects.
Monofilament thread (invisible thread)
Made of 100% transparent nylon or polyester and comes in clear and smoke. Strong with little stretch. Most popular sizes are .004 and .005Can be used for machine sewing and for overlock stitching. Can be used for applique, crafts, machine quilting, and other home decor projects. Cover with a net when machine sewing to prevent tangling.
All purpose thread
Most usually made from cotton wrapped polyester. Cotton giving it the strength and polyester gives the flexibility and stretch.
Cotton thread fibers have been mercerized to add strength, ability to take dye, and color fastness.
**mercerized is a finishing process to make thread smooth and take dye better, lustrous appearance. First invented by John Mercer in 1851.
