Welcome from NY--the country part!
You are so creative!! Those that don't follow a pattern and make their own way--well, we always pay attention and are inspired. :D
My only suggestion is to sew a bit around the ones you fused on--I just used some fusible stuff and a few corners came up. If it was a wall hanging it might not be as important--but if it's a quilt, I'd definitely secure those babies!
Speaking of babies--looks like you're a new mommy?
