One common mistake is choosing body fusing cloth based only on price or a GSM number. Two materials with similar specifications may still differ in hand-feel, bonding behaviour and suitability for a particular garment. Sampling should therefore be part of every serious sourcing decision.
Another mistake is approving fusible interlining without testing it on the factory’s own equipment. Heat, pressure and dwell time affect how the adhesive performs. A supplier sample may appear suitable until it is processed through a different production press.
Buyers should also avoid treating the first approved sample as enough for every future order. Keeping records and checking incoming deliveries against the original reference helps identify variation before production begins. Consistent purchasing checks can prevent small sourcing mistakes from becoming large production losses.
