I used a June Taylor fussy cut ruler that was 6 1/2 Square for Pot holder and I cut enough for 30 pot holders and they were supposed to be 8 1/2 inches. I cut fronts and backs and cotton batting and insule bright. I spent all day and when I was done I looked at the video again and read below and I had this gut feeling and sure enough. I was just looking at the ruler she was using and did not know there was also a 8 1/2 inside cut also. What should I do with all these 6 and 1/2 inch squares. There is no rime or reason on the fabrics. I cut from cute valentine and St pacrick's to motorcycles. Oh darn. I should have read more below the video. Live and learn.
