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

Thanks to the great folks at Best Buy I'm no longer angry. The Thread set I received was exactly like the negative reviews I read. You can not use that thread on those spools on any machine. I tried three. I did rewind the spools onto bobbins. Just throw the spool on the floor to let it unwind by itself. Hold the thread and wind the bobbin by hand. There is a twist when the manufacturer originally wound them when it gets too tight it snaps and makes quite a mess. They very well may have made some attempt to relieve the situation by putting a cap on one end of the spool. You would never know it. I didn't notice the twist till I dropped a spool and decided I would let it feed off the floor instead of on the machine spindle. After winding about 20 feet the little critter jumps right into your lap.On the plus side this is extraordinarily beautiful, strong thread. If you are going to do hand embroidery go for it. If you are going to use a machine ask yourself if the price warrants the hassle.update:The bobbins I wound are fine till I needed a color and didn't have any empty bobbins. My daughter suggested I purchase a thread holder. I will when I find one I want. Until then I've placed the spool in a tall narrow glass and periodically check on it. Seems to unwind quite efficiently that way. I've used it on several projects and am very impressed with the quality and color. The price is worth the effort for me. I will order it again if it is available. It is a top quality product at a very reasonable price.
