I hope I uploaded my photos correctly.

Need some opinions on whether to sew this 1930's print blocks (top photo- sorry it makes you dizzy since its upside down) together or to add a white sashing in between each block? I am leaning towards sashing.

I have extra leftover fabric (bottom photo) that I could incorporate into a border but not sure how do it? Any ideas are welcome.

Thank you,
Pat
