The Pattern

Start with a foundation chain in multiples of 3 plus 2 for your turning chain

Row 1. In 4th chain from hook make a dc (the turning chain counts as your first stitch) dc in the next stitch. *Chain 3 and skip the next 3 stitches then dc in the next 3 stitches*

row 1
3 double crochet ch 3, skip 3

Repeat between *and* when you get to the last 3 stitches, chain 2 and pull up a loop in the last stitch and change colour then chain 1

Joining your 3rd colour
Change colour in the last stitch of the row

Turn

Row 2. In the same stitch as the colour change, make the alternate turning chain. In the 2 skipped chains in the foundation chain, make a dc. *Chain 3. Make a dc in each of the next skipped foundation chains*

Pull up a loop so your stitches are pulled up high
Pull up a loop to the height of your turning chain

 repeat between *and* when you get to the last 3 stitches, chain 2 and pull up a loop in the last stitch and change colour and chain 1.

Row 3. In the same stitch as the colour change, make the alternate turning chain. In the 2 skipped chains 2 rows below, make a dc. *Chain 3. Make a dc in each of the next skipped stitches 2 rows below*

Your stitches are made in the skipped stitches 2 rows below

repeat between *and* when you get to the last 3 stitches, chain 2 and pull up a loop in the last stitch and change colour and chain 1.

Repeat row 3 until you reach the height you need. Then we need to make a finishing row.
