I haven't yet started looking at material yet, but just the "thinking about it what to do" part WAS a lot of fun!
Here's what I did: I took out pictures I'd had printed out of my two Havs and started looking at them with the quilt blocks in mind. I was looking for a good image of either Sammy or Ricky, in action or just posing. I placed my photo up on my glass patio door (it could be any window) during the day and with a sheet of white paper over it, I gently traced the form of my Havanese. You don't want to leave an imprint of your pencil on the photo.
I then played around with it a bit and scanned my sketches. I used Word to insert the saved drawings and enlarged them, and mirror-imaged some of them until I got to where I liked things. Printed those out in several sizes.
I used two 8 1/2 "x11 papers to create 10"x10" (or 11x11) block and started placing the cut out images I'd just printed here and there to come up with scenes I like. Here's an example.....
I am not using this image. I kind of divided the dog up so that I could picture using diff. patterns on the same applique. I got inspiration from your amazing Havs, Julie, both from the Ricky/Tori and Delilah/Samson blocks you made.
Now if only I didn't have such a crappy sewing machine and have to do the small appliques by hand!
