One participant I think is making a knit top with a flounce at the bottom. (Well, I know who you are, but I don't want to speak out of turn, or embarrass you). An adjustment has to be made for a full tummy, which means that a flounce at the bottom of the bodice will also need altering.
Now I am only a home sewer and not a pattern maker, but I just wondered if this could be the solution. Below please see a very quick sketch of a flounce. The upper edge attaches to the bodice bottom:
You will notice I have marked dotted lines within the flounce - one at the centre front, and then two either side. I would slash and spread the intervening sections of flounce, much like you would for an A-Line skirt. Because the outer edge of the flounce is a wider circle (remember geometry here), the top of the spread area will be narrower than the bottom:
Not very clear here, but I was sketching these over my early morning cuppa before going to the office to do some bills! But if you look you will see I have tried to keep the trajectory of the curve.
I would trace my pattern piece first, so that I have something to cut and play with - and the "real" pattern is there to be traced again if you make a mistake.
I would measure the width of my altered bodice front pieces. I would then know how wide my inner flounce curve (the seam that meets the bodice bottom) needs to be. I would divide this amount by 4 (the number of cuts I am going to make ) and then spread the cuts by that amount. Keep the trajectory of the curve, and you will note that the bottom area will spread too, but by a slightly greater amount.
I don't think it would matter if the curve flattens a bit - I haven't actually seen the pattern pieces, only the picture of the top. I think you could sew out any excess at the sides. Have a play with a scrap first.
Other people may have better suggestions, but I thought, for what it is worth, this idea may work.
Does anyone else have another way of solving this problem?
