It has taken all day to rectify my immense threading error, but at last, here it is, finally off the loom.
I really like it and it turned out as I expected, which is always a bonus.
It has since been washed and my shrinkage calculation proved right, so I now know it will fit the stool top.
Upholstery job and cushion making activities next week as I still have a couple of pieces of fabric to make.
And now, look at my buttons !
