Mimisharon,
Hang in there Babe! You'll be caught up before you know it. Just do these blocks by 'little bits'. A little bit today and a little bit tomorrow, a little bit here adn a little bit there and before you know it it'll be a quilt top.
AND if that proverbial creek does rise your quilt will only be a little damp.
Remember...
Quilting has no time lines!
