Wisthout thinking carefully about “what will happen” we might make a suppression of the under-arm seam as illustrated on Figure 3. Squaring down from A to locate B, we could mark out so much on each side of the latter point and fix C and D. (And this very thing has been done very many times.) Perhaps we have overlooked the relative distances of C-E and D-F, and what effect the ultimate suppression will have on those distances. We must also think of the distance 1-2.
