When the first layer is complete, wrap twice more, first vertically, then again horizontally, further compressing the waistline to fit each layer more closely, and smoothing over wrinkles this causes with more tape.

When finished, have the "wrappee" bend slightly to reveal her waistline, and mark it (and any other points you want identified) with marker or later with colored tape.

Mark the waist. Bending slightly will reveal your wrappee's natural waist. Mark all around with a permanent marker.		Cut carefully up the back. Keep your hand between the tee shirt and the wrappee's body to avoid cutting undergarments or flesh.

Cut off the form and T-shirt layer at center back with your other hand between scissors and body to avoid cutting undergarments (or the wrappee!). Then close the form with additional tape, stuff it with poly batting, and place it on a stand (read on for stand ideas). Joyce's finished form has a polished look, similar to an industrial dress form.
