I will most likely do pieced and applique blocks after deciding on a theme. Thanks to everyone for their input.
2 heads are better than one and I appreciate your great ideas to consider.
The challenge is due in July so I have time to dream after looking through my scraps.
I do like the advice to "think beyond the obvious" such as flower pots and window sill boxes as habitats for flowers. What fun ideas you smart ladies have given me. thanks. stay tuned!
