I have just finished one not even a week ago and it was not fast. 300 squares - 100 each for front, batting and backing. I quilted every square differently and I quilted on the back so that I can see what the heck I am doing (I used natural muslin for backing mixed with beige and whir on white leftover fabric. To make matters worse or more interesting I used about a dozen is different color threads on the back. I had my doubts but after I was done and it all got put together and washed it turned out to be one of the best quilts I ever made. Everybody loves it, especially the back. I had 100 squares on which I practiced free motion quilting. I have to be honest, by the time I was done I hade a huge boost of confidence. I can honestly say now that I can do FMQ with little or no problems. Good luck! According to everything you wrote your quilt is going to be a beauty. I am 100% sure of that.
