1. On one side, match up the side seams on the clutch body with the lining; pin. With the clutch body facing up, start at the top finished edge on the side seam and stitch in the ditch 3 1/2 inches down (see Diagram 13). Repeat on the other side of the clutch body.
2. To give the clutch shape, fold a 1-1/4-inch angled pleat into one side seam, beginning at the top and tapering the pleat to end 3 1/2 inches down (see Diagram 14). Press the folds in place. Repeat on the remaining side seam. Note: The absence of ultraheavyweight interfacing in the area you're pleating should enable you to make crisp folds.
3. Attach a vintage pin onto the right side of the tab's wide end, covering the stitching where the hook-and-loop tape was sewn.
4. Fold the clutch back over the clutch front, aligning the hook-and-loop closures, to complete the clutch.
