Review on Dual Duty XP General Purpose Thread 250yds Navy: The Ultimate Sewing Essential by Nicole Mcleod

A selection of shades of gray almost the same color, 3 of which are almost indistinguishable from each other. They do not represent the image. There is no reason to have 4 colors that are so close together unless you have a very specific reason for it. There are #630, #620, #600 and #520. #520 is the only noticeable difference as it's light gray - the other 3 look the same and you'll have a hard time deciding which to use in place of the other. *Also, mine didn't arrive in a box and was just taped together in black plastic by a ShipzNow seller, so pay attention to who the seller is! Please note I also bought the blue range which was boxed and had a good range of distinctly different colours.
