Review on Vibrant 40-Spool Polyester Embroidery Thread Set For Brother, Janome, Singer, And More - 500M Spools, 40Wt - 4 Sets Available At Threadart! by David Alexander

First off, for some reason Best Buy has this set listed twice, one that ships from Best Buy and the other ships directly from ThreadArt. Each listing has their own reviews. I had mine ship directly from ThreadArt which took about a week. I bought this set as my starter threads, thinking I would upgrade to better quality threads once I get the hang of the embroidery. I have made several projects with this set and could not be happier. As you can see from the pictures, the threads are lustrous and all the colors are vibrant. The threads themselves are very slippery and want to unravel from the spool which often caused the thread to get caught between the spool and the spool holder on my machine. This problem was solved by using a separate vertical spool holder. I did have few breaks or shreds with these threads (I would say every other project, depending on complexity). So when I was low on black and white I decided to buy Madeira and Isacord replacements and compare the brands. The ThreadArt threads are actually the shiniest of the three brands, Isacord being the dullest. The major difference I noticed are the spools and how threads sit on them. Both Madeira and Isacord spools are much better quality and the threads do not slip off of them as easily as the ThreadArt ones do. Both Madeira and Isacord spools have a thread lock so that threads don't unravel while stored, I ended up putting a net mesh over the ThreadArt ones to prevent the unraveling. But as far as the quality of sewing, I did not see any difference. In fact the black Madeira thread shredded on me during the test, causing sparse stitches. I really do love the luster of ThreadArt and will buy these again despite the inconveniences. One thing to note, although these are ThreadArt threads, they are labeled with Brother numbers, so to replace exact same color from ThreadArt individually, you need to convert the number to ThreadArt (they have a conversion chart on their website).
