I am making a table runner. The middle square needs to be 9 1/2 inches (which includes the 1/4 inch seams.---so finished, it will be 9 inches). I am choosing to make that middle square in a pinwheel. I have made 3 samples and used every ratio that I can remember and this darn square just does not turn out to be 9 1/2 ".
A friend said that there is a magic formula for pinwheels---I cannot find this formula anywhere online..
This shouldn't be that difficult. What am I doing wrong? Is there a formula to make this easier? This is a simple table runner and the comment was that I should be able to complete it while my cup of tea cools down. So far I have spent 2 days on this square and can't get it right---ugh!
Thank you for any help that you can provide.
