Can I just buy any sample I want?

We don’t recommend it because then you won’t know if it comes in your needed product style or size. It’s best to first locate the product you want, then follow the measuring instructions to make sure it comes in the size you need, and only then purchase its underlying sample. There is no point in blindly adding a lot of fabric samples to your shopping cart only to later find out they’re not available in your desired product or size.
