I have an adjustable dress form that I've always used when sewing. It's the kind that has dials at the neck, bust, waist and hips to adjust. I found it at a clearance sale at Sears over 40 years ago. It has a fabric covering with foam underneath and it's great for pinning the pieces together then for making adjustments as you go. I used to keep my mom's measurements on hand and then I could make clothes for her without her ever seeing them until they were done - and I knew they would fit! It was also great when I made a dress for my daughter because I didn't have to bug her to keep trying it on. The form came in two sizes - one was for the 28-36 sizes and the other for larger sizes.
Has anyone tried e-bay, Craigslist or sites like kijiji to see if there are some used ones?
