No wonder you love doing these - they turn out so great!
They look like fun. Keep enjoying what you like to do.
I think these are terrific & to help out with the corners a quick tip for you: before you turn them back to the right side trim each corner on an angle it helps make them easier to stay sharp & flip nicely too! hope this helps! I think the corners are terrific on all of them sew your doing just fine! Hugs Loralye
