I decided I really wanted to make something that would/could be around for a long time and would suit whatever nursery colours they ended up having.
I have included the pattern I used at the bottom of this post.
I've always liked ripple blankets and thought they were much harder than this, but I would recommend them to anyone!
----------------------------
PATTERN
With white, chain about 1.5 times as wide as you want your blanket to be. Don't worry if it is too long- you can always cut off the excess of your chain once you've started you valleys and peaks and can see how much you like.
I like three single crochet up the side of the hill, 3 crochet into the next single crochet, then three single crochet don the other side of the hill. Then, to make the valley, skip two single crochet and start the three going up the hill again.
At the last "side" of a peak you'll need to skip a single crochet and then turn as normal and skip another as you up the side again- otherwise your piece gradually increases- something I missed the first time I tried this.
Here is the pattern, properly laid out:
Row 1: With white , single crochet (sc) in 2nd chain (ch) from hook, sc in next 2 ch, *3 sc in next ch, sc in next 3 ch, skip (sk) next 2 ch, sc in next 3 ch; repeat from * to last 4 ch, 3 sc in next ch, sc in next 3 ch - 13 ripples.
Row 2: Ch 1, turn, skip (sk) first st, sc in next 3 sts, *3 sc in next st, sc in next 3 sts, sk next 2 sts, sc in next 3 sts; rep from * to last 5 sts, 3 sc in next st, sc in next 2 sts, sk next st, sc in last st.
Then I did 6 rows of white and two of the colours.

Happy crocheting!
