I've been gradually working my way through a most interesting blog site
I put the cling wrap back sections on top of heavy paper to draft up the sloper. No drama with the back which I slit from the centre shoulder seam to the point of the shoulder so it would lay flat. This is the shoulder dart which I can manipulate later.
I then put the front on the paper and slit from the side seam to the bust point but it won't lie flat. It gets a 'dart' shaped fold at the armscye.
I have a large and low bust and these silly thin arms and I've had this problem before when making a sloper. If I accomodate my thin arms and put the curve of the armhole high up under the arm (which is where I want it and especially for this style of top) the curve of the armhole looks wrong - too severe and acute an angle. to make it lie flat at the armscye, I get a slight buckle in the top edge of the cut at the bust, but my bust point on the cling film is certainly where it is on my body. I can't understand it.
I wondered if I tape the side seam to bust point cut back together again and then cut from the shoulder seam to the bust point to form a dart and from the waist to the bust point to form a dart (rather like a Princess seam) and just held together at the bust point by a sliver of film, if this might make the cling wrap body double then lay flat at the armscye????
Does anyone have any thoughts or suggestions as to what to do to fit a big low bust and thin, thin arms from my cling flim double please?
