Best guess on dimensions are roughly 18X6X12.5 - not sure if they are in the right order and I didn't allowance for seams. She has you sew main panel to bottom which is 6X18 making it 18" with the other side being 12.5" and then the width of the bottom is 6". But I have one ???? and will count on one of you .... From what I can tell, other than the lining, I could use just FQs ... right?
