Granny Square Afghan

I have a granny square afghan http://crochet.about.com/od/crochet-pictures/tp/Crochet-Inspiration-10-Beautiful-Granny-Square-Blankets.htm that my mother made.  I am not sure how I ended up owning it after my mother's death, but for me, it is a blessing that I have this afghan.  For several years, I have been using a fleece throw on top of my sheet, and a blanket as an extra supplement to the sheet and comforter on my bed. When I started using the granny square afghan, I did not need the extra blanket, or the fleece throw.  I am blessed to have this granny square afghan that my mother crocheted.
