Preserve Color, Strength, and Shine in Every Skein
Embroidery and thread projects are made to last, but even the finest thread needs care. COSMO threads—No. 25 cotton, variegated Seasons, Nishikiito metallic, and hidamari® Sashiko—are crafted in Japan for longevity and beauty. With proper storage, handling, and maintenance, your threads can stay vibrant, tangle-free, and ready for your next creative project.
Why Thread Care Matters
Threads can suffer from fading, fraying, tangles, and the quiet wear of dust or moisture. A few thoughtful habits keep every skein, cone, and metallic spool as beautiful as the day it came out of the box—so finished pieces can stay bright on the wall for years.

- Fading or color change from sunlight or improper storage
- Fraying or splitting during stitching, especially with fine strands
- Tangles and knots that slow stitching and damage fibers
- Dust or moisture that affects sheen and hand feel
Organizing and Storing Threads
COSMO threads come in a variety of formats—skeins, pre-cut lengths, cones, and metallic spools. Each deserves a slightly different approach.
No. 25 Floss
Care tips
Solid No. 25 is the workhorse of most stitch baskets. Keep it sorted, labeled, and protected from light so color families stay clear and skeins stay neat.

- Storage: Wind skeins onto bobbins or keep in original packaging.
- Organization: Use a floss box or labeled divider for easy selection.
- Tip: Keep skeins separated by color family to avoid tangling and color confusion.
COSMO Seasons Variegated Floss
Care tips
Subtle color gradations are part of what makes Seasons special. Avoid tightly compressing skeins so the strand stays smooth and the shading easy to read.

- Storage: Because subtle color gradations matter, avoid tightly compressing skeins.
- Tip: Store flat or loosely coiled to prevent flattening and preserve smooth shading.
Nishikiito Metallic Thread
Care tips
Metallic finishes love gentle handling. Keep spools secure, away from rough edges, and use only the strands you need.

- Storage: Spools should remain in original packaging or thread holders to prevent unravelling.
- Tip: Metallic finishes can snag; always keep away from rough surfaces or abrasive containers.
- Strand handling: Some finishes are fine and delicate—use only the number of strands needed and handle gently.
hidamari® Sashiko Thread
Care tips
Cone-wound sashiko cotton wants steady tension and upright storage so the soft matte finish stays intact from the first yard to the last.

- Storage: Cones are best stored vertically or in small bins to keep threads from unwinding.
- Tip: Avoid pulling too aggressively; smooth, steady tension preserves the soft matte finish.
Maintaining Threads During Use
Handling tips
How you handle thread at the needle matters as much as how you store it on the shelf.

- Wash hands before stitching to prevent oils or dirt transferring to threads.
- Avoid pulling threads too hard—this can stretch or distort fibers.
- For metallic threads (Nishikiito), consider threading a needle through a threader to reduce friction.
Preventing Tangling
Most tangles start with too much length or too much twist. Keep working lengths short and strands calm.
- Pull only the length needed for each project.
- For long threads, gently loop or coil before use.
- Keep threads separated and avoid twisting multiple strands together unnecessarily.
Preserving Color and Luster
Light, moisture, and dust are the quiet enemies of color and shine. A cool, dry, dark home for your stash does most of the work.

- Store threads in a cool, dry, dark place away from direct sunlight.
- Avoid exposure to moisture or high humidity, especially for cotton threads.
- Metallic threads benefit from storage in dust-free containers to maintain shine.
Advanced Tips for Multi-Thread Projects
Layering No. 25, Seasons, Nishikiito, and hidamari opens texture and depth—if each thread is handled on its own terms until it meets the needle.
- Layer No. 25 cotton, Seasons variegated, and Nishikiito metallic to create texture, depth, and shimmer.
- When combining threads, keep metallic strands separate until ready to stitch, to avoid fraying.
- Use hidamari® behind or beneath other threads for subtle texture in sashiko or large motifs.
Practical Storage Solutions
The best storage is the setup you’ll actually use—clear labels, separated finishes, and a place for every format.

- Floss boxes and dividers: perfect for organizing multiple skeins.
- Thread cone bins: vertical storage to keep cones upright.
- Spool racks: ideal for Nishikiito and other metallic threads.
- Zip pouches or small containers: convenient for kits or project-specific thread sets.
