Hello,
I had to go to the manufacturer's website, MCG Textiles to try and find this information since they are the ones who put these kits together and this is the only information I could find on the product:
Giraffes at Sunset 39.5x26" latch hook rug kit. Kit includes full color chart, how-to instructions, 3.75 mesh rug canvas and pre-cut Acrylic rug yarn. Latch hook tool not included.
Since they are using pre-cut acrylic yarn I am guessing they use the brand they sell on their website and that is 320 strands, approximately 2 1/2" long. Hope this helps but this is all of the information I could find. Thank you.
