Engineering Drawings for Bed Sheets

I need precise technical diagrams created for a bed sheet design I have. The deliverables should include three diagrams that clearly outline sewing patterns. It's essential that the drawings are accurate, well-detailed, and formatted as PDFs. These diagrams will be used as a reference for production, so clarity and precision are crucial. These are my drawings - obviously, drafting is not a skill that I have. I want to clearly show the top sheet of a set of bed linens with the top sheet having a cup at the bottom just like the bottom sheet normally has and a drape from that corner so the top sheet will look much as it does with todays sheets. I need a drawing of the entire bed showing the cupping and then a detailed look at the bed foot enclosed by the top sheet cup.
