Clutch with shaped flap — trial leather patterns

Clutch with shaped flap: adjust dimensions, PDF, SVG and DXF patterns, and A4 printing. Trial construction based on publicly available references; check the dimensions and assembly on a mock-up.

Clutch with shaped flap: construction example

The diagram shows a 350 × 210 mm layout: sections of 110, 130 and 110 mm. A width of 210 mm, a back panel of 130 mm and a front of 110 mm were used. A 15 mm transition was added for thickness; this is a trial adaptation of the diagram. Adjust the strap and fastener. The roses are illustration decor, not a cutting line.

Body width	210
Body height	130
Body depth	15
Flap drop	100
Wrist loop length	300
Loop width	12
Leather thickness	1.5
Stitch offset from edge	4
Additional seam allowance	0

Parts in this example

The dimensions below are derived from the geometric model. The parts list changes with the parameters and enabled options.

Piece	Size, mm
Front, back and shaped flap · Spread	210.0 × 363.8
Side insert · left	15.0 × 110.0
Side insert · Right	15.0 × 110.0
Wrist loop	300.0 × 12.0

How the size changes the pattern piece

Calculation example: the “body width” parameter was changed from 210 to 231 mm. The diagram shows the “Front, back panel and shaped flap piece before and after recalculation at the same scale. · layout before and after recalculation at the same scale.

Clutch with shaped flap: Body width 210 and 231 mm — The dimensions below the drawing refer to the outer cut-edge contour. This is the result of a geometric calculation.

The files were generated using the standard VLOTHO CAD export from the parameters specified above. They show the model geometry and do not replace checking the product in the material.

PDF A4, 8 sheets PDF patterns, 1:1 SVG patterns, 1:1 DXF patterns, mm JSON project

PDF A4 automatically selects portrait or landscape pages and rotates the pieces to reduce the number of sheets. For assembly, a 10 mm overlap, numbers, and alignment marks are provided. The standard PDF contains one piece per page. Both variants include a 100 mm test segment. For your own dimensions, modify the project and export a new PDF. How to print patterns at 1:1 scale.

What to check before cutting

The patterns have not been verified by sewing. Dimensions are approximate and not to scale; assemble a mock-up first. The card contains a generated illustration of the proposed product.

VLOTHO CAD builds a geometric prototype. Allowances for bending, skiving, assembly thickness, and construction methods are determined by your material. Start with a paper mockup and a trial piece.

How to get a pattern for your dimensions

Open the model and set the dimensions in millimeters. To reproduce the tabular example, first load its JSON.
Check the parts list and enabled options. Adjust the seam and dimensions for your material.
Save the project and export a new pattern set. After changing the dimensions, the previous files no longer correspond to the project.

Dimension reference for this model: Stitching line. Dimensions in the parts table and the outer cut contour may differ due to the seam allowance. How to check seam allowances and stitching lines.
