Ravelry: Hexa-ghan pattern by verybusymonkey Worsted / 10 ply wpi) ? US 10 - mm This blanket could easily be adapted for any yarn/gauge you want. It would make an excellent sock blanket and there’s NO SEAMING NEEDED – yeah!
Start with 3 colors. Each block is 9 stitches so for however wide you want the blanket, count in 9 to get your foundation (always make it an uneven number of "blocks) eg: 19 blocks(makes it about long) stitches then add 4 sc for the foundation row.
