I started with the largest which uses the 10 inch squares, then went to the smaller which uses the 5 inch squares and this week went to the smaller two which use the 3 1/2 and 2 1/2 inch squares. I have twisters on the brain recently it seems. I have at least three projects planned for these rulers already cut waiting to go. As hot as it has been here in Mississippi there isn't anything I'd rather do than sew so I guess it's okay I have projects lined up...
