I hope your week is off to a good start. I have just been visiting another blogger, who like most of us, dreads the dilemma of fabric measurement in relation to yards, or parts of yards.
Being my usual inquisitive self, it got me wondering too, so with a bit of searching, I came across this and thought there might be other crafters who might like to view it.
The site link also offers conversion to metric measurement, and suggested quilt sizes.
I hope you find something useful here.
Happy crafting, Jenny
