Doubling Yourself for Sewing, Fitting & Pattern Drafting

Make yourself a duct tape double upon which to drape and fit clothing and patterns. If you are sewing for the 18thC, you would wear your stays or corset under the T-shirt prior to wrapping. Lace up the back and draw your chemise throat/collar line on the duct tape double and you would be ready to either draft patterns or drape yards of fabric into your own robes.

Another method is the Moulage as taught by Ecole Guerre-Lavigne, using measuring and sewing of a muslin «second skin», which could also be stuffed and placed around a dressform foundation to make your own pattern-drafting-fitting mannequin.
