I've got a new toy to go along with my passion for sewing.
Very helpful: to see mistakes, big mistakes that I should have seen while I was picking stitches for the neck border.
So I just had to undo and redo the whole border.
And now, I can see the buttons do not match the yarn. That is a shame because this yarn is so gorgeous, it deserves the right button... I'll change them at the first opportunity. I promise I will...
