I had a little bit more of the dark green acetate taffeta lying around, and I thought the Tentacles looked a little bare and in need of embellishment. Step one was a gathered ruffle about 7 inches wide before hemming. I used three lines of stitching for a nice tight gather, and zigzag stitched it to the 1878 fantail skirt, hanging down about two inches lower than the hem. The skirt was just a bit too short upon examination of last year's Halloween pictures.
I'm looking out for some dark green venise lace about 3 or 4 inches wide. So far, all I found was an esty seller who seemed to be all out. I wonder if I buy just plain white, some bridal shop can dye it for me. I might also need some velvet ribbon or an inch-wide row of ruching out of the same taffeta to hide the edge of the ruffle. To me, Victorian-inspired Lovecraftian creature costumes look better with heavy embellishment.
