I can do the math if I know the equation but in this case I don't even know that there IS an equation other than trial and error! lol which I would REALLY like to avoid at this point.
So here is the question, what if any is the equation for making boarders. I know measure the quilt length first and add side boarders I know all that mess, but when you are putting strips together to make a boarder and you are doing the 45 degree seams how much extra do I need to add to the total length so I am not wasting a bunch of fabric? Does it depend on how wide your boarder is going to be? Should I add X inches for each seam needed to get the total length?
Maybe I am just making it way to complicated and I don't have to add anything other than the usual 1/4 inch to either piece for seam. lol It just seems like your cutting way more off when doing a 45 degree match up.

Good question. I can't wait to see the responses.
I love to make mitered corners, because I love the look of them. But to date I still waste a lot of fabric because I can't even figure an approximate.

Are you asking how much extra border length on each side to MITER the border corners?
No math, if your border is 5" wide all around, then your borders need to be 10" longer + a little fudge room if you want to be safe.
IOW - each border corner needs to extend at least to the outside edge of the connecting border.

If the border is cut 8" wide and the quilt center is X inches long, wouldn't I need an additional 16" in length? So the border would be cut x+16, right?

The formula is X + 2Y + 1 inch
X = length of quilt top (normal border length)
Y = width of border
1 inch = 1 inch
You need the normal length for the border plus twice the width of the border plus one inch.
A 60 inch quilt with an 8 inch border would need a minumum of:
60 + 8 + 8 + 1 = 77
X = length of quilt top (normal border length)
Y = width of border
1 inch = 1 inch
You need the normal length for the border plus twice the width of the border plus one inch.
