Hello,
The Craft Trim Yarn is carded, 3-ply 100% acrylic yarn and is 20 yards. This color #8 Hot Yellow is definitely neon is color. Craft Trim's dye lots change frequently so the batch we have right now the color is a tad more on the neon green side. The next batch we get, it may be more neon yellow so it all depends on their dye lots. Hope this helps!
