Check care instructions first
Fabric preparation depends on how the finished item will be cleaned. If the project will be washed, prepare the fabric in a way that matches its intended care, when the fiber and finish allow it. Some fabrics can shrink, bleed color or change texture. Delicate, coated or dry-clean-only materials may need a different approach.
Treat matching components consistently. A lining, interfacing or trim that shrinks differently from the outer fabric can distort the finished piece. The Sewing & Craft Alliance recommends checking fabric care directions and preparing materials before cutting (fabric preparation guide).
Check the grain
On woven fabric, the lengthwise and crosswise threads should meet at right angles. If the grain is skewed, a project can twist or hang unevenly. Align the selvages and inspect the cut edge before laying out pattern pieces. For some woven fabrics, pulling a crosswise thread can help reveal a straight cutting line; this does not work equally well on every fabric.
Knits behave differently from woven cotton or linen. Avoid pulling the fabric into shape by force. Follow the pattern and material guidance, and test on an offcut if the fabric is slippery or highly stretchy.
Press, then lay out
Press wrinkles out before placing pattern pieces. Use a temperature suitable for the fiber and any surface treatment. Lift and lower the iron rather than dragging it when the fabric could stretch or distort. Let the fabric cool and settle before measuring.
Follow the pattern layout for the selected size and fabric width. Check grainline arrows, nap, print direction and any fold placement. Pin or weight the pattern pieces so they do not shift while cutting. If you are unsure about shrinkage or color transfer, test a small scrap using the intended care method first.
