Common fabric widths and their typical uses:
- 36" Width: Quilting cotton, some specialty fabrics
- 45" Width: Most fashion fabrics, cotton prints
- 54" Width: Upholstery, home decor fabrics
- 60" Width: Wide fashion fabrics, knits
- 72-108" Width: Quilting backings, wide home decor

Frequently Asked Questions
How do I account for pattern matching?
Add one pattern repeat length for each major piece that needs matching. For plaids or large prints, you may need additional fabric to match patterns across seams. Always check the pattern layout guide for specific requirements.
What's the difference between nap and no nap?
Fabrics with nap (velvet, corduroy) or directional prints must be cut in the same direction. This typically requires more fabric than fabrics without nap, where pieces can be rotated to maximize fabric usage.
How much extra should I buy for mistakes?
For beginners, add 1/2 yard extra for small projects and up to 1 yard for large projects. Experienced sewists might need less, but having extra fabric is always helpful for repairs or matching pieces.
Should I pre-wash my fabric?
Yes, pre-wash fabric as you plan to wash the finished item. This prevents unwanted shrinkage and ensures your final project fits correctly. Some fabrics may shrink up to 10%, especially natural fibers.
