Here
you can see how I decided to decrease the Dayflower Lace pattern; the partial
flower in the last few rows of lace is divided by a YO at its lower
edge, which I felt kept it from looking too blocky. If I decreased
further, I could perhaps have made that last flower look more like a
mini version of the others--but then the underbust circumference would
have been too small.
An interesting problem with this sort of decreasing is that for each stitch decreased within the stitch pattern, you will have the same number of stitches decreased as there are repeats of the pattern; thus, for this top, every time I decrease one stitch within the Dayflower lace panel, I decrease 14 sts per round. The problem arises if/when you try to write a pattern for multiple sizes. I'll use a simple example, a sweater with a lace pattern lower border, in which I want to use decreases within the lace to get from hip to waist circumference. Generally, the amount decreased from hip to waist doesn't vary much from size to size.
But
if I want to write the pattern for hip/bust sizes 34 (40, 46, 52), with
a gauge of 5 sts per inch, and I have 8 (10, 12, 14) repeats of my lace
stitch pattern respectively, then if I decrease 1 st per repeat, I now
have decreased 8 (10, 12, 14) sts in one row--or roughly 1 1/2 (2, 2
1/2, 3) inches--a markedly different amount for each size. Not so
different with one decrease, maybe, but if I want to decrease 6 inches
to shape the waist, then I have to make 4 decreases for size 34, 3 for
size 40, probably 3 for size 46 (5 inches--close enough), and 2 for
size 52--meaning three different decrease methods. If I tried to
decrease the same way for each size, I might end up with (for example)
4 1/2 (6, 7 1/2, 9) inches decreased--which in size 52 is probably too
much for any except the best-endowed AND wasp-waisted.
Other options? Compensate by making the hips proportionally larger in the larger sizes, or perhaps leaving a few of the repeats unchanged in the center back/front, or at the sides, in the larger sizes. One solution might work well for a particular garment and stitch pattern, and not for another. But I think you can see why this type of decreasing is not that common, except perhaps in hat patterns.
Oh yes, these pictures also show attempts 1 & 2 at the underbust band, with eyelet holes for a twisted cord tie; I felt that the first one didn't have a clear enough delineation of the band/lace transition, and also that the bust increases (several rows above the eyelet holes) were too visible.
