FAQ
What GSM is best for custom hoodie

How do I verify fabric quality before bulk
A: Request swatches with complete specifications: fiber content, GSM, shrinkage rate, colorfastness rating, and care instructions. Test physical properties yourself before approval.
What causes common quality issues
A: Fabric shrinkage (from improper pre-shrinking), color bleeding (dye quality), seam failure (stitch type or thread quality), and dimension instability (poor pattern making).
Can I request custom fabric development
A: Yes, leading manufacturers like Bless Clothing offer custom fabric development including unique blends, weights, and treatments. This typically adds 15-25 days to lead time and requires larger minimum orders.
How to ensure ethical manufacturing
A: Request factory audits (BSCI, WRAP, SA8000), ask for worker condition documentation, verify certifications, and consider third-party inspection services.
