I am using the DIY Quilt Calcs spreadsheet to do the number crunching for my TQ.
I am making a rectangular top quilt for this Labor Day weekend with a final dimension of 48wx78L and a baffle height of 2". The cut dimensions are inner(51x81) outer(57x87).
My "sewing margin" is set at 1.5". What is that exactly?
Based on the inner shell cut lengths, I'm guessing the sewing margin is the amount of material I have to sew up the edges (.75" rolled hem), but for the outer, there seems to be extra material that I'm not sure what to do with. There is 4.5" of extra material around the edge outer shell, or 9" total.
Here's the break down for one edge (totaling 4.5 inches). 2 inches for baffle height, 1.5 inches for seam margin?, which leaves 1 inch extra. I'm not sure what the extra inch is for. When I look at the formula for the cut dimensions, which is based on the whole not one edge, I see =((FinishedLength+(2*BaffleHeight))+2)+(2*SewingMargin). In my case =(78+(2*2))+2)+(2*1.5) What is the bold and underlined 2 for?
What is the difference between sewing margin and hem?
This is my first quilt, and I'm just not sure what I'm missing.
Any clarification you can offer would be great.
Thanks
