I love it! That pillow is terrific! Don't fret about not having a plan. When I start with a plan, I inevitably change it the minute I start sewing. Makes for some creative decision making!
I have this book and have tried doing a corgi as my dog, Gummybear, is a corgi. But I couldn't get the blanket stitch to look nice. I think it might be the thread I'm using. Can you share what kind of thread you are using?
