I finished the top this morning. It is one big square (7x7) up of 10" blocks. I am hoping to get it finished soon so we can start using it. I have been debating between the two Laurie Smith fabrics, pictured below, for the backing. I finally decided on the orange mosaic fabric and now I am not sure if I will have enough. I may have exactly enough if I don't have any cutting errors. Keep your fingers crossed :)
Thank you Sheila, Christina, and Sarah for all of your input and spare squares, it was most appreciated :)
