I found piles of precut strips in the church stash. I think they were cut for sashing; at 2.5" wide, the navy strips were perfect! First, sew the strips together on the diagonal.
Then iron neatly in half, wrong sides together.
Roll up on empty toilet paper rolls! The one on the right is (hopefully) enough for the two church quilts. The one on the left is for the patriotic quilt.
