Needle Knowledge

Klasse needles.

Here's something I didn't know. Quality needles are made to break. Really.

Klassé needles, an industry standard for a century and a quarter, are designed to break in the event of a problem. Why? A bent needle does a lot of damage to expensive equipment and hooped fabrics.

Normally, you would think a broken needle means poor manufacturing. While that may be true with inferior brands, quality needle breakage means a problem elsewhere: wrong type for the fabric, bad tension, improper alignment, or damaged tip.

A needle is to the machine embroiderer what the paintbrush was to Picasso. The right tools create beautiful works on canvas and on fabric.

Sizes: Too Big, Too Little, or Just Right?

Needles range in size from 60/8 to 120/16 (metric/U.S. shaft diameter). The lower the numbers, the finer the needle. Why does that matter? It is important to know how threads and needles work together.

Thread numbers are just the opposite of needle numbers. The larger the thread number, the more fine the thread. If you use a large diameter thread (12 wt.) in a needle with a small shaft diameter or small eye (75/11), it will shred and break. Likewise, if you use a fine, heirloom thread (60 wt.) in a needle with a large eye, it will swim. Stitches will not be uniform, the hole will be too large for the thread, and coverage will be inconsistent.

A general rule of thumb is that the thread diameter should be 40 percent of the needle size. Needle grooves are designed to best stitch within this ratio.

Types: A Needle for All Purposes

One needle does not fit all. Needles are constructed differently according to how they should be used. You wouldn't use the same type of needle when sewing leather and satin. Points are more rounded for stretch fabrics and sharper for quilting. Eyes are longer for topstitching or when using metallic threads.

Many embroiderers use topstitch needles for everything: piecing, quilting, embroidery, and applique. Often, it is a matter of preference. Klassé has an excellent reference for determining the needle type needed and sizes available.

Endurance

A unique curve above the eye makes the Klassé needle stronger than its counterparts and encourages a longer lifespan than traditional needles.

Some embroiderers recommend changing needles every 8-10 hours, others say 20 hours, and some say change it when you are experiencing problems. At any rate, when in doubt, change it out. You've spent thousands of dollars on an embroidery machine and good money on fabric; it doesn't make sense to skimp on the needles.

The Klassé needle bundle provides a great selection of needle types for a variety of embroidery and heirloom projects and shipping is FREE!

Thanks for this great info.


I really liked reading your article.  Very good information and well presented - Thank you!


Glad you liked it.


Any other topics you are interested in? Let me know!


Many who sew or machine embroider don't realize how important it is to not only have the correct needle type and size, but also to change them often.


Some of these crafters may remember their Mother or Grandmother never change the needle unless it broke!  And, chose the needle size according to what they could best see (eye of the needle) for threading.


I change my needles according to what I will be sewing or embroidering and never had a breakage problem until I used Klasse brand.  


There is usually a reference chart for the type of sewing/embroidery in the manual for the machine.  However, what the manufacture (as of now) has not taken into consideration is the use of adhesives for machine embroidery.  


The right needle type when adhesive stabilizer (sticky back or spray) is the Titanium coated needle.  It stays cool and does not soften the adhesive.  If you have ever had the needle and thread to get gummy, breaking the thread - switch to the Titanium coated needle.  


I had such good results with this type needle, I bought them in bulk and used them regardless of the stabilizer - adhesive or not.
