@luxire - the Brisbane Moss canvas fabrics are a nice addition, but note that the weights listed are per square meter, not per running meter, which is how fabric weights are typically quoted. 310 grams/square meter is roughly equivalent to 465g (15-16oz) per running meter.
Could you let us know if the weights listed for other fabrics on the Luxire website are measured by square meter?
Running meter and GSM are both used to describe fabric weight.
We have standardized it to GSM as it is independent of the fabric width measurement in the roll.
