This design is stitched with all Crescent Colors floss. They use names, not numbers, for their floss. The correct names are listed under the supplies tab on the item page. Some sites have charts with the closest colors lf DMC floss, but these are overdyed/hand dyed floss and no other floss brand will.match perfectly. Just search/google for "conversion chart Crescent Colors to.DMC".
Please note that you will need more than one skein of three colors. You can see this in the supply list in a column that appears just before the price of each skein.
