Perfect. I love the walls (even if there are no visible doors).
I agree with your decision about the outer border. Love this!
I have that fabric, too!! This is a great use for it! What a fun quilt!
These little scientists are just too cute. I really like the color combo. I checked back through your posts of your progress and was impressed with your use of the frame on the ruler to cut the center squares. I'll have to remember that.
I just love this so much!
This is looking great!
