Back panel of Altar Cloth

I have a week or two to finish the last panel for the churc's altar cloth. It can be used the way it is (three sides), but our priest-in-charge, Paul Briggs, asked if I could get the last side done for this summer. I have quite a few more squares to finish, then to arrange them and 'slap a back on' it and hopefully attach it to the top's edge. All I can seay is it's a good thing I save stuff! ( I almost put the remaining scraps in the 'orphan' block box at church to use on another quilt.)
