Here is another group of cards created from Jean's collage sheet.
This sheet inspired a lot of people to work abstractly, and I guess that's what I like about these challenges - it pushes us to see in new ways.
Here are Ellen's geometric cards:

Gina created her signature eye on her first card:

Frances added some simple paint and pen embellishment to great effect:
Leslie took the triangular approach to her geometric abstracts.

Lucinda added paints and glazing and perhaps some image transfer (?) to her collage.
I really really love being able to hold all of these in my hands for a while. I study them, admire them, learn from them and get inspired by them.
