This blanket has a seed stitch border and rows of hearts (each row in one of four colors) alternating with garter/seed stitch stripes in a fifth background color.

This is a heart scarf that I made for a child. It is a seed stitch border with a row of hearts down the middle. It is reversible in that the row of hearts is purl against a knit background on one side and knit against a purl background on the other.

This blanket has six colors (C1 to C6), combined pairwise along the blanket in a shifting combination. Any six colors can be used.
