Sewing planning guides

Practical explanations that support the calculators and help you avoid expensive cutting mistakes.

Fabric length depends on roll width, piece count, seam allowance, shrinkage and print direction—not just total area.

Seam allowance is the fabric outside the stitching line. Its size depends on construction, fabric and finishing method.

Cotton, linen and many knits can change size after washing.

Pattern repeat is the distance before a printed design repeats.

Grain affects drape, stretch and stability.

Measure the usable pole or track, not just the glass.

Choose a zip, envelope back or hotel opening before cutting.

Fabric cost alone is not the full cost.

The best saving happens before the first cut.

Prewashing reduces later shrinkage and removes some finishes.

A useful inventory prevents duplicate purchases.

A written plan reduces interruptions and forgotten supplies.
