Thanks for all the compliments on the block. I did make another one on Sunday & it turns out that it is a 9 1/2" unfinished block...so mine was close.
I checked Roolen's original blog where she posted the directions in 2009 and she said it was a 9" x 9" finished block (without seams). I'm thinking if I make a full lap quilt like that I might put a small red sashing between each block. How do you think that would look? It's hard for me to visualize things like that. Maybe someday I'll invest in EQ7 so I can see things before I actually make them. For the time I will just use my design wall to audition what looks best.
