Instructions include patternmaking for an A-line skirt and a pencil skirt. Patterns are created in half-scale but verbal instructions are for full-scale female size 10.
Yes, whatever seam allowance you have on the half-scale will double when you go to full-scale. So if it's a 5mm seam on the half-scale, it will be 1cm on the full-scale one, just by making it pattern double in size.
