A simple "cross" quilt can be made by (for example):
top row: 5 blocks, background
row two: 2 bkgd, 1 cross, 2 bkgd
row three: 1 bkgd, 3 cross, 1 bkgd
rows 4 - 6: 2 bkgd, 1 cross, 2 bkgd
row seven: 5 blocks bkgd.
The cross blocks may be any pattern, pieced of yellow and white, with the background (same or another block) pieced of darker colors.
