Those poor nauga hides... (other thread joke).
Yeah,a 9 sq ft. hide if you cut from inside out, then you should come out with enough lace.
This pic was wiped off somewhere, for the actual squares and a look at the columns. And, I only had 15 going across I think, not 16.
So, each column should be about 11 feet of lace give or take how tall ya are. Therefore, you would have 1 strand = 11 feet. 17 columns x 11= approx 187 ft of lace. So, we should cut give or take, about 62 yards for the skirt, I think. I somehow remember cutting around 85 yards for some reason. Oh well, better have more than less, cause once you cut a column's worth of lace then the rest of that lace is discarded if it doesn't equal 10-12 feet. I once figured it using 2PiR or 3.14xdiameter somehow. I felt so smart.. and my brain hurt like nuts, but I had 3 strands left over, I was that close! 2 x 3.14 x 12inches (which is a 2 ft circle)would give you like 75 inches of lace for just 1 time around that width.
I won't sacrifice my brain again... I'm sorry, I can't give you anything exact. But even a small 2 ft circle would give you TONS of lace.(2ft circle is 4 sq feet of leather used) But yeah, like 9 sq. ft should be enough (so that you can cut a 3 ft circle). So long as you are practiced enough.
And don't forget to tug on the back of the strand once you get it started. It will help lots.
