Yeah, they are quite cleavagey on me. It doesn't help that I've always had about half a cup size difference between left and right, so either I have one cup fitting right and one too big (unsupportive) or one fitting right and one too small (overflowing) whichever sort of bra I go for.

I have been failing to get my sewing machine mended / serviced because of residual feelings from the last time I tried home sewing that (a) the amount of pattern adjustment needed is too much of a bother and (b) the kind of clothes that I like and that fit me tend to require more awkward sewing curved bits of material together than I am competent to deal with, but seeing what you produce is very inspiring.
