Frequently Asked Questions
What is the "standard" seam allowance?
In commercial patterns, it is almost always 1.5cm (5/8 inch). However, this is not always the *best* allowance. For lightweight silks, a smaller French seam is better. For thick wools, a 1.5cm-2cm seam is needed to press flat.
What if my fabric isn't listed?
Choose the closest match. The main factor is weight. "Linen" and "quilting cotton" would both be "Medium-weight". "Brocade" or "Denim" would be "Heavyweight".
Does this tool work for Imperial (inches)?
Yes! The tool provides the recommendation in both Centimetres and Inches, so you can use whichever you are comfortable with.
