3D Cushion Model with Extra Cloth Stitched outside

I need a 3D model of a cushion with an extra cloth stitched outside. The model should be detailed, showcasing the stitching and the fabric folds (no texture need just 3D model). The final deliverable should be in OBJ format.

Ideal Skills & Experience:
- Proficient in 3D modeling software
- Experience in creating detailed product models
- Able to deliver in specified format (OBJ)
