Thanks Flimsy and Teacow
A gentle but elegant way in which to start the week off, indeed!
Was able to start in the top right and steadily work around clockwise until coming to COSTLY as my last one in not all that long after.
Thanks to Flimsy and Teacow. Enjoyable. I took a long time getting COSTLY but otherwise all went smoothly.
