This is a modified pattern from an afghan pattern project of mine titled “Pearl -June” from LA’s Birthstone. You can see an all white afghan version on Carol Prior’s site

The background rows are white/varigated pastels, the bobble rows are blue, pink and cream in this picture. I have made it w/ a backgound of varigated white and pastels w/ bobbles including greens and yellow combinations also.
There is another picture on my project “crocheted bobbles afghan.”
I love this pattern and have used it often for baby blankets.
