How to crochet a ripple stitch lap blanket?

Question

Does anyone know of a very easy to follow ripple stitch crochet pattern for a lap blanket/afghan/throw? Not a full size blanket and not a baby one. Just something to throw over while watching TV. How many chain stitches should I start with and what to do next? Maybe about 4 ft wide? I am not sure how to calculate how many chains I need for that width or how many ripples I need. Thanks!

Answer 1

Four feet wide?  An adult size afghan is smaller than a blanket and is usually around 40-45" wide by 60" or so inches long.  

Here's a pattern for one that measures 45" x 60" in the ripple design:

Answer 2

Here is a link for a ripple pattern.

Make the chain and start the pattern and when it is the width you want, turn and carry on with the pattern as written.
