Design Details for the Ripple Pattern

The ripple is created by repeating increases and decreases
This forms the wave pattern across each row
Once you complete the first few rows, the pattern becomes very easy to follow

I used cream for the thin stripes that alternate with the bright rows of colour. The cream rows are worked in single crochet stitches and the contrast rows in different colors are worked in double crochet stitches.

The cream yarn adds a freshness to the overall palette that I love. The pattern shows a slight difference in both sides and both of them are beautiful!

Is this ripple blanket beginner-friendly?
Yes, it’s an easy pattern. Once you understand the increases and decreases, it becomes very simple to repeat.

Why is my ripple blanket not straight?
This usually means stitches are missed at the peaks or valleys. Counting stitches or using markers can help.
