@GOODVIBE Prism by DMC sells multicolor thread with a similar color combo. I don’t think that you can buy it individually, but if you just search up tye dye prism embroidery floss, then there’s a pack of strings (some multicolored, some just plain colors) and there’s 2 skeins of blue, pink, and white multicolor thread in the pack.
@humen1o1 to post pics you go to what ever pattern you want to take a photo and click add photo then choose the file that the pic is in hope this helps 😊
