I appreciate the comments and encouragement! I'm working my way around the borders of donated top now, I'm just doing a simple feather with an echo (and a wobbly echo at that!) - I'm sure as Mereth suggested on the hearts that by the time I'm done with the quilt these will somewhat perfected too (hopefully).
This is the first time I've used the pebbles on a quilt and I love them. No matter how poorly I feel like I'm quilting them, when I'm done and step back they look great! I think it's because you quilt around them 2-3 times so they don't have to be perfect.
I was second guessing using the heart fill. I loved what Mereth did on her banner so maybe next time I have a large open space I'll use a meander that includes a variety of shapes.
