More bustles and more shirring elastic.... More trapese-line top (from my book) variations. This time, a 2-metre piece of voile from Clear It ($5 per metre) was folded top and bottom to make a dress length diamond shape...and then the shirring elastic was put into action! So yes... more poncing about and more swishing of bustly bits. (Anyone would think that bustles didn't go out of fashion over 100 years ago).
Oh, and here's a large zipper rose (instructions are also in Le Book).
EDITED TO ADD: I just found a weekend where I can schedule a Pattern-Free Top Workshop - if you need a bit of help to get started with this method... or just want a fun sewing day. Details here.
