Method:
- Cut 5 swatches from the different places of the fabric.
- Weight all test swatches accurately and calculate the average weight of swatches.
- Multiply the average weight of swatches by 100 to calculate the GSM of the sample fabric. (Normally, the area of round GSM cutter is 1/100 square meters.)
