Shipping boxes to UK via USPS - wording for customs forms?

We're going to start sending a few boxes of clothing (and some small breakables) over to my mum-in-law's in the UK. Will be using US Post Office. What wording should we use on the customs forms? ("Used clothing and used personal effects" ??) Looks like the form we need is a 2976A.

Thanks!

They should give you the correct form at the post office when you go to ship it - I shipped 4 boxes back to the UK in 2008... I just wrote 'personal papers and clothing' on them.

I also put " no commercial value" on all of my forms.

Sorry, can't remember where I first read to do that .

Cheers, friends!

for clothes, the clerk at the post office I had been shipping through advised me to combine shirts and pants on one line (as you only get 4 lines on the form)
