Well I knows that !! But tis vair tiny squares and I wanted to make sure . I have been looking at chef square fabric and can find trousers in fine squares am still searching for fabric by yard. Or perhaps if it is for patching then trews could be cut up.
I have used them a lot....you can design your own or you should have a look at existing patterns on there as they have tonnes...and you can even choose your own fabric type...so cotton, upholstery fabric or stretchy stuff...it's a great site...US based but not too epensive...and they're good at keeping in touch when you wait for your orders.
