The buyer of a loom band dress who bid £170,000 on eBay has pulled out of the deal.
Helen Wright from Prestatyn and Kathryn Burnand from Wrexham made the dress from 20,000 loom bands, but an email arrived on Monday saying the deal was off.
The woman, who lives in Surrey, said she couldn't afford the £170,100 price tag plus £7 postage.
The dress is believed to be the first of its kind and captured the world's attention.
Helen, her daughter Sian and Kathryn appeared on ITV Wales News, the One Show, Newsround, and their story was told in newspapers as far away as Australia and New Zealand.
Helen, who works as a barmaid in Archies in Prestatyn said they had really enjoyed the the "whirlwind" and still thought anything over £50 would be a bonus. They now have a guide from eBay helping them with another bidder.
– Helen Wright
"We don't have to take the next highest bidder and Ebay said we should look at all the bidders' feedback before deciding. We have one chance of offering it to a bidder from the last auction then we can go for a relisting. I've whittled it down to six buyers who all put in bids over the £150,000 mark.

A zoo in Pembrokeshire is welcoming Wales' first ever pride of African lions.
The pride, which is made up of one adult male, and a family of lionesses and juvenile lions have made the journey from Longleat Safari Park to Folly Farm, helping to make the attraction a flagship exhibit for Wales.
The arrival of the pride marks the completion of a £500,000 project to build a purpose-built two acre enclosure for the lions.
The lion's new enclosure is made up of four dens/bedrooms, and from today, visitors will be able to come and see them.
Alongside the lion house there is an education centre, themed as a fully-equipped ranger's hut. It will provide visitors with information on African lions, and the work carried out to monitor and protect them.
It's estimated the numbers of African lions in the wild have declined by as much as 30% in the last ten years.
– Jon Cracknell, Director of Animal Operations, Longleat Safari Park
"The new lion enclosure at Folly Farm is extremely impressive. When I was given a tour of the flagship exhibit I was overwhelmed by the great deal of thought that has gone into every aspect of the design of the enclosure.
It is an enclosure that Folly Farm should be very proud of and I know that our lions will be very happy to make it their new home."
