Last year after I bought the stunningly beautiful blue silk which I have been afraid to cut I bought a printed linen in a similar pattern to make an under gown and test out a cutting diagram before cutting into the silk. The linen was still patiently waiting in my stash, untouched, but I have finally begun putting it to it's intended use!
My fabric was cut evenly at the top of the pattern repeat at one end and a bit raggedly and off the repeat at the other. My skirt length varies from 42" in front to 45" in back and the pattern repeat of my fabric happens to fit exactly into 45" sections so-working from the good end- I cut one full width of fabric, 45" long for the front panel. since I want a train on this dress I used the somewhat raggedy end of the dress length for the back of the skirt. I picked a pattern transition point about 15" up from the edge and measured my 45" skirt length from there. I will eventually curve the button edge of this panel to form the train.
I am using the burial dress of Elanore of Toledo as my starting point for the patterning of the skirt but fabric constraints prevent my skirt from being quite so lavish. After I cut both the front and back panels I had about one and a half skirt lengths of fabric left. I decided to split this piece lengthwise into three sections, 1/4, 1/2, 1/4, so that I would have the full center of the panel to use when making my bodice and as much length as possible for making the sleeves. The 1/4 width panes are being split into triangles and inserted between the front and back panels to create a greater sweep of the skirt at the hemline and help the train to drape gracefully.
Now I just have to sew while keeping my fingers crossed that it works!
As to the sewing itself, I'm finally trying the period method of hemming each piece and then whip stitching them together. I think I like it. :)
