Could you give me some specific recommendations for each type of Sulky Thread?

Sulky Rayon:

30 wt: Available in 102 Solid Colors and 54 Variegated and Multi-Colors. Works best in my LA machine. It also works well in the bobbin. Use a 3.5 needle and loosen the top tension slightly.

40 wt: Available in 333 Solid Colors and 55 Variegated and Multi-Colors. Use Sulky 40 wt. in the bobbin when you use Sulky 30 wt. Rayon, Metallic, Sliver or Holoshimmer on the top. You can also use Sulky 40 wt Rayon in the needle along with Sliver or Holoshimmer to help them work better.

Washing restrictions for Rayon: While Rayons are colorfast in hot and cold water, you should not use bleach, or detergents that contain whiteners or optical brighteners, etc. (Sulky Poly Deco thread is good for quilts that will need lots of washing, or washing in bleach.)

Sulky 40 wt. Poly Deco:
Available in 138 Solid Colors. Works extremely well on LA machines in both the needle and bobbin. If you are having trouble with metallics, etc. in the needle, try Poly Deco in the bobbin. Poly Deco is excellent in both the needle and bobbin because it is smooth and strong. Use needle size 3.5-4.0

Sulky Invisible:
Works well in either the needle or bobbin, or both. Sulky Invisible is a very fine .004 continuous poly monofilament thread. Many quilting teachers have recommended Sulky Invisible for years because of its excellent runability. You may need to lower either needle and/or bobbin tension. Wind bobbin very SLOWLY and NOT completely full. Use Needle size 3.5-4.0

Sulky Metallics:
I usually use a 4.0 needle with Sulky Metallics. Lower the top tension and sew slowly. I like to put metallics in the refrigerator for a while before using them. Lengthen the stitch. Sew for a shorter amount of time. Avoid quick motions and designs that cross over.

  • Original Metallics - While I have used this in the needle by itself, I usually combine it with Invisible, Rayon, Poly Deco, etc. to lower the possibility of breakage. It is possible to use Sulky Original Metallics in the bobbin.
  • Sliver Metallic - I usually run either Sulky Invisible, Holoshimmer, Rayon, or Poly Deco along with Sliver. Some LA Quilters use Sulky Sliver in the bobbin.
  • Holoshimmer Metallic - Works extremely well on LA machines. Run Sulky Holoshimmer by itself or in combination with any of the Sulky threads. Put a soft/smooth Sulky thread in the bobbin.


Sulky Cottons: Both 30 wt. and the heavier 12 wt. are now available in 66 beautiful Solid Colors and 42 fabulous new Multi-colored Blendables that change colors every couple of inches.

30 wt. - works well in either the needle or bobbin, or both together.
12 wt. - also works well in either the needle or bobbin, but not well in both needle and bobbin at the same time. I usually have 30 wt. running in the bobbin with 12 wt. on top. The heavier 12 wt. is great for bobbin work (with 30 wt. in the needle).

Use at least a 4.0 needle with 30 wt. and 12 wt. Sulky Cottons. If you experience any thread breakage in the needle when using 12 wt. on the top, try changing to a 4.5 or 5.0 needle.

Lengthen the stitch, especially for the 12 wt., and use for smooth quilting designs with few points so that there is no issue with thread build-up at the points. Clean the bobbin area frequently when using the 30 wt. or 12 wt. cottons. Also, it may help to lessen your speed a little, if needed.

The Sulky Blendables have 42 great short-run color combinations so they blend in or accent your quilts beautifully.

General Comments:

Loosen your needle tension and check the bobbin tension as well. Both should be looser since these are heavier threads than you might normally use.

I put the spool on the small spool holder in the top middle of my machine. Mount the spool so that the thread comes from the back, over the top of the spool, toward the front of the machine. If you have the new threading mechanism, I suggest that you just come straight forward to the 3 hole guide and not go backwards into the new tensioner.

With some of the Sulky threads, I just make one pass across the quilt, then tie off and go back to the beginning for the next row or section of free-motion.

Avoid pantographs that have a lot of sharp points where the thread can build up. Try for smooth easy movement of the machine.

Try putting the thread in the fridge or freezer for a while. Any threads like to be cool and moist.

Don't quilt for too long a time, especially if you are having problems. Take a break and have your favorite beverage; put your feet up; let the machine, needle and, most importantly YOU, cool off before trying again.

Sulky Stabilizers:

Sulky Tear-Easy can be used to make designs to stitch over instead of marking the quilt.

Sulky Totally Stable can be used the same way. These can be "attached" to the quilt with Sulky KK2000 Temporary Spray Adhesive or pins.

Sulky Solvy or Super Solvy are good for designs to see through to quilt.

Sulky Ultra Solvy is great for stitching lace, appliqueacute;s, constructing faux "designer" fabric for garments and scarves, etc.

Sulky Fabri-Solvy is the NEWEST Sulky Solvy. It has the firmness and feel of fabric but it washes away.

Sulky Soft 'n Sheer Cut Away - I have enjoyed using Soft 'n Sheer as an inner layer in several of my quilted garments.

Sulky Sticky+ can be used to make templates of designs to stitch around by layering several pieces together.
