I’ve been wanting to make a ripple with two different sizes of points. A few sketches and little math was all it took; the very first one came out about 35” wide, just like I wanted!

I love how its stripes wriggle across the blanket ~ thus the name, Wriggly Ripple! :-)

My ‘regular’ ripples have 6 points with 10 dcs per side.
This one has 9 points - 5 large points that have 9 dcs per side, which alternate with 4 small points that have 4 dcs.

Stripe Pattern: 3 rows burgundy, 2 rows, lt. rasp., 1 row white

My free Wriggly Ripple Pattern is here.

And the annotated version of it (with tips) is here.
