The blue denim thread is very practical when having to hem blue jeans. Normally, I have to use either a black or dark blue thread. This Dual Duty Denim Thread that I recently purchased should work very well. I didn't plan to use the thread the moment it was delivered, but the next time I have to sew blue denim, this is what I definitely will use. One thing though; the photograph makes the spool look much bigger than it actually is, so that was a bit disappointing.
Nice thick thread, did not know but I got a 3 pack!!! Cannot beat the price when it retails for around $5 for one!!!! I think would be great for top stitching or anything that needs a sturdy thread. Cannot complain, AMAZON is the best!!!
