How to flatten a washable tablecloth

[123fushia]

New washable tablecloth bought. It was folded up into a plastic bag. I can't iron it to get the creases out, have hung it on the line in an attempt to flatten it but still very creased. Any ideas about what to do please?

The creases came out of mine once it had been on the table for a while.

Can you not iron on reverse, that's what I did to mine

Will try that.... Maybe on the reverse on a low heat under tea towel. Thanks
