First, I draw the basic skirt block, and then cut it and spread the parts to get a flared long skirt pattern. I was methodicall thorough and through, making first a toile, which already proved perfect, and then cutting the real fabric on the true bias.
I followed all my recently learnt advices from Khalje, Shaeffer and Hirsh to sew the zipper, to apply the underlining, to cut the fabric with the toile and then stitching it all around, to let the skirt hang before marking the hem, etc, etc.
The result was simply perfect.
On with my following project, hello paternmaking, goodbye commercial patterns!
