I sew most weekends, from hemming school uniforms to patching jeans and making curtains, and for years I bought whatever thread was on sale, until a seam split on a pair of trousers my son wore to school. That sent me back to the brand my mother used, Coats and Clark, and I spent the last month sewing with five of their all purpose threads across cotton, denim, and stretch knits. Some spools ran like a dream, one tangled more than I liked, and the differences showed up in the seams.

Why Coats Clark All Purpose Sewing Thread Is Necessary
Thread is the smallest part of any sewing project and the easiest to blame when a seam fails, yet most people buy it as an afterthought. A good all purpose thread holds its tension, feeds smoothly, and keeps its strength after dozens of washes, while a cheap spool shreds in the needle, tangles in the bobbin, and leaves seams that split at the worst moment. The difference between the two is a few coins per project.
Coats and Clark has been the default thread in sewing boxes for generations, and there is a reason for that. The Dual Duty construction wraps a polyester core in a polyester cover, which gives the thread strength without stiffness, and the range covers every common color and weight. When I reach for a spool I have used a hundred times, I know exactly how it will behave, and that predictability is worth more than any bargain.
Keeping the right thread on hand also saves time, because the wrong color or weight means either a visible seam or a trip to the store mid project. A black and a white spool, plus the color you use most, covers nearly every job a home sewer faces. Buy the good thread once, and the seams you sew will outlast the clothes you sew them into.
My Buying Guides on Coats Clark All Purpose Sewing Thread
Why I Looked for Coats Clark All Purpose Sewing Thread
I was tired of seams splitting and thread shredding in the needle, so I went back to the brand my mother trusted and tested the full all purpose range.
My shortlist had to sew cotton, denim, and knits cleanly, hold up in the wash, and come in the colors I actually use.
What I Check Before Buying
First I check the weight and fiber, since a medium 35wt polyester thread suits most home sewing, while heavier fabrics need a stronger option.
I also check the yardage per spool and the color, because a short spool runs out mid project and the wrong shade shows on light fabric.
My Preference for Polyester or Cotton Thread
For everyday sewing I prefer polyester, because it is stronger, resists shrinking, and holds its color through many washes.
I still keep cotton thread for heirloom quilting and natural fiber projects, where the softer hand and matte finish matter more.
What I Look for in Quality
I look for smooth, even thread with no thick and thin spots, since uneven thread causes skipped stitches and tension problems.
I also check that the spool unwinds cleanly and the thread does not fray at the needle, which are the first signs of a poor quality spool.
How I Compare Prices
I compare the cost per yard rather than the spool price, since a 400 yard spool at a fair price beats a short bargain spool every time.
I also watch for multi packs, because buying black and white together usually costs less than buying them one at a time.
My Tips for Choosing the Right One
Start with black and white in the standard all purpose weight, then add the color you use most, and keep a heavy duty spool for denim.
Match the needle size to the thread weight, test the tension on a scrap first, and always wind a fresh bobbin before a long seam.
Final Thoughts
After a month of sewing with five Coats and Clark threads, the six pack of white all purpose thread is the best value for a regular sewer, and the black and white two pack is the best starting kit. The Dual Duty construction, the smooth feed, and the strength after washing all held up across cotton, denim, and knits. If you sew often, stock the basics and stop buying bargain thread.
If you sew fine fabrics or do a lot of hand work, the Dual Duty XP version is worth the small step up for its smoother stitch formation. Whichever spool you choose, match the weight to your fabric, keep your machine clean, and let the thread do its job. Good thread is cheap insurance for every seam you sew.
