Here is the stitch I used to make this blanket! If you make one, I'd love to see.
Foundation chain - Multiple of 6 sts + 1
Row 1: 5 DC in 4th ch from hook, *skip 2 ch, 1 SC in net ch, skip 2 ch, 5 DC in next ch, repeat from * ending 1 SC in last ch. Turn
(I just picked up the next color as I turned each row, not cutting the previous color and worked them up so that I didn't have a gazillion ends to weave in)
Row 2: 3 ch, 2 DC in first sc, *skip 2 dc, 1 SC in next dc (the center dc of 5), skip 2 dc, 5 DC in next sc repeat * ending 3 DC in 1 ch. Turn
Row 3: 1 ch, skip first 3 DC, *5 DC in next sc, skip 2 DC, 1 sc in next dc (the center dc of 5), skip 2 dc, repeat from * ending 1 sc in 3rd of 3 ch, turn.
Repeat rows 2 & 3 until desired length.
Super simple, fast, but oh so mind numbing. Beautiful end results though which makes it all worth it.
Best of Luck!
