The color pattern I used was (1 row of pink, 1 row of yellow, 1 row of blue) repeated, ending with a yellow row. I did the border in blue.
Here's how to make it:
Row 1: sc in 2nd chain from hook, sk 2, (5 dc in next chain, sk 2, sc, sk 2) across, 3 dc in last ch
Row 2: ch 1, turn, sc in first dc, sk 2, (5 dc in sc, sk 2, sc in middle dc, sk 2) across, 3 dc in last sc
Repeat Row 2 until work reaches desired length.
Border:Top Row: (counts as one side of Round 1) sc in first two dc, (3 hdc, 3 sc) across, ending with 2 hdc, (2 hdc, 1 sc) in corner.
Round 1: sc around, 3 sc in each corner
Round 2: dc around, 5 dc in each corner
Round 3: sc around, 3 sc in each corner
Round 4: sc around, 3 sc in each corner
Round 5: dc around, 5 dc in each corner
I made this using I Love this Yarn in Banana (yellow), sky blue (blue), and Pizzazz Pink (pink) yarn with a J hook.
