I can build blocks, draft patterns, manipulate patterns, tweak patterns, I can sketch designs, I can interprete design sketch.I can even sew. I have got knowledge about beading and stoning, to mention a few.
Building blocks where patterns ,for example bodices pattern ,are derived which are manipulated to get desired style/designs and placed on fabrics to cut before passing down to tailors to put together and other personnel involved in production and then supervised to the end for nice and neat outcome of outfits.
