Canvas cotton check

I bought this canvas cotton woven check fabric from a local interior fabric shop to make my Nephews wigwam. I chose a canvas fabric as it is extremely hardwearing and I wanted the wigwam to last. I used 315cm Fabric of this fabric (Width 137cm (54") wide), to make my wigwam.

I have tried to find out the make of the fabric but to no avail, so if anyone knows where you can buy this fabric online, please let me know in the comments so I can share the information, thanks x
