Hand Embroidery:

The thin quality of Blending Filament allows you to create elements of subtle light reflection. It is often combined with cotton, wool or another thread type, in the same needle, to create a random metallic sparkle. The addition of one or two strands does not add weight to your thread, so you can use the needle size that accommodates the stranded cotton. Vary the amount of highlight or shimmer you want to add to a design by using one or more strands; use a single strand for the most subtlety or two strands for added effect.

Overstitching & Texture: 

There's more to Blending Filament than just 'blending,' however. You can also use Blending Filament by itself to overstitch, bringing a reflective highlight or glow to a particular spot. Also, use a single strand of Blending Filament by itself in half-cross stitches for backgrounds on fabric; it creates a slight texture and subtle shimmer.

Tips on using Kreinik Blending Filament in hand work: 

  1. Use short lengths of thread — about 45cm (18 inches) or less — to avoid excessive abrasion when pulling the thread through the ground fabric or canvas. The more a strand is pulled through fabric or canvas, the more 'wear' it causes on the thread. Using shorter lengths will maintain the quality of the thread, plus reduce tangling as shorter lengths are easier to control (less knotting!). If you are stitching on fabric, use a needle large enough to 'open' the hole in the fabric sufficiently and allow the thread(s) to go through more easily; this reduces friction and fraying.
  2. If combining Blending Filament with another thread type in a needle, you may wish to moisten the filament together with the other thread with a slightly damp, soft cosmetic sponge. This can help to control both thread types as they work together in your needle.
  3. Stitch slowly with Blending Filament to achieve more control and uniformity in stitching.
  4. Let your needle hang frequently to let the thread untwist and thus reduce knotting.
  5. If using Hi Lustre Blending Filament, lay the filament flat and smooth as you stitch to allow maximum light reflection. Think of it as a tiny ribbon; using a laying tool can help prevent twisting, or simply use your finger to lay the thread.

Machine Embroidery: 

Blending Filament creates three-dimensional effects whether used in the needle or the bobbin of a sewing machine with specific embroidery patterns or free-motion techniques. It is ideal for art quilts and wearable art. Blending Filament also creates delicate reflective highlights in programmed patterns on embroidery machines. Kreinik offers an extensive color range to match fabric or mood.

Tips on using Kreinik Blending Filament with a sewing machine or serger: 

  1. When using Blending Filament in the needle, try a Metalfil or Metallica needle. You will need to loosen the top tension and adjust the bottom tension; practice until you get a combination that works with your machine, stitches, and fabric choice.
  2. When using Blending Filament in the bobbin for needle lace or other effects, experiment with different tension settings until you find a combination that achieves the look you want on your fabric. A 50m reel of Blending Filament fills a bobbin nicely.
  3. You can also combine Blending Filament with other threads or use it alone in a serger. Estimate 10 times the length to be sewn for thread yardage when using without mixing with other threads.


Kreinik Blending Filament is hand or machine washable and dry cleanable. Cool water is recommended. Do not use bleach. It can also be tumble-dried on low setting. When ironing a finished piece containing Blending Filament, do not iron directly on the thread; use a cloth, and do not use steam.
