Bernat Softee yarn in Soft Peach, Antique White, Mint, and Pale Blue - Amounts will vary depending on how many squares you make/size of blanket you want.
Notes: I alternated the 3 middle colors for each square for the sake of interest, but kept the borders white and plan to assemble them all with white. The color options are up to you, so I didn't put in the names of the colors, but will just refer to the colors as Color 1, 2, 3 and 4. You get to choose what order to put them in. ;) The pattern is worked from the center out, if that helps with your choices. I would recommend tying a small knot at the end of each round to help the yarn stay in place, as I am always afraid that changing yarns a lot will make a blanket fall apart!
