I used 5" blocks to make my 9 patches which made a 13" finished block. I arranged them 4 wide by 5 high and added a 1" (finished) border followed by a 3" (finished) border. This made a quilt approx. 60" x 73" which is a nice size for cuddling up to watch TV.
It went really fast. Although I have past sewing experience, I am a beginner quilter and this was really fun, quick and easy pattern.
