Need Fabric

Hi friends!
When I started on the second pillow sham , I realized I needed some more white fabric. I will pick up some the next time I go to town.
I went looking for some fabric to extend the backing I had picked.

I added this across the bottom. So now I am looking for some more fabric to take care of the sides
I need 15 or 16 inch's on each side.
Maybe I can get the sides on and sandwich it soon.
Since Mother's Day is this weekend I may not get any sewing done.
Happy Mother's Day
Hugs
