Water it will be - thanks so much for your replies! That's the one that I thought would be better with the beachy nature of the quilt. (And I think I'll be better at FMQing the more horizontal lines rather than all those loops.)
I didn't use the lighthouses when I made the quilt - the pic is from EQ - as they were oversized for the other beachy motifs I used - beach chairs, sea gulls and small scale lighthouses. I'll post a pic when it's done.
Thanks again for taking the time to look.
