I can't remember who needed this information but here are the colors of the thread/floss for the sampler:
Light Pink - jp Coats 65/DMC 605
Dark Pink - jp Coats 59B/DMC 603
Blue - jp Coats 24A/DMC 813
Green jp Coats 109/DMC 987
These are from the original set so if you have trouble getting these, I can go to the store and see what currently matches. Good Luck!
